Word formation root words

Cambridge Exam English (Part 3): Word formation

In this part of the exam the candidate is given the most basic form of a word, known as “the root” form. You need to change the prefix or suffix to adapt the word into the correct form and make it fit in the 8 gaps in the text so that it makes perfect sense.

The best way to do this exercise is to focus on the word class (type of word: noun, verb, adjective, adverb), grammar (singular or plural, verb tenses, +/-) and spelling. The words must be spelled correctly and if a capital letter is needed, it must be used.

You ought to think of this as a 3 step process:

  1. What type of word do I want? Noun, verb, adjective or adverb.
  2. What grammar is needed? Singular or plural noun, the tense of the verb
  3. Is it affirmative or negative? Which prefix or suffix do I need?

To aid the candidate´s understanding of this part of the exam. we have included a prefix and suffix list, high frequency root words list and also example sentences with answers in the extra resource section.

The best way to improve this part of the exam is to focus on the root words and learn all of the different word classes for each one. We have provided a comprehensive list for you.

Root and Affixes

Affixation is the most common word formation process in English. Words are formed by adding affixes to roots.

Roots can be free or bound morphemes. They cannot be further analyzed into smaller parts. They form the base forms of the words.

  1. Free roots are free morphemes. They can stand alone to function as words.

    Examples:

    re

    collect

    , bi

    lingual

    , un

    easy

    , mis

    lead

    ,

    hard

    ly,

    attract

    ive

  2. Bound roots are bound morphemes. They cannot stand alone to function as words because they are no longer used in Modern English.

    Examples:

Affixes are bound morphemes. They can be classified into prefixes and suffixes in English.

  1. A prefix is an affix added to the beginning of other morphemes to form a word.

    Examples:

    dis

    like,

    de

    activate,

    in

    adequate,

    im

    mobile,

    mis

    leading,

    un

    accountable

    en

    durable,

    under

    achieve,

    over

    developed,

    pre

    requisite,

    post

    graduate,

    re

    cycle

  2. A suffix is an affix added to the end of other morphemes to form a word.

    Examples:

    admirable, fruitful, ambitious, enjoyment, eagerness, standardize, cowardly,

    younger, processing, McDonald‘s, assignments, decides, decided

Can you tell the different functions of the red suffixes and the blue suffixes?

Teachers frequently debate this question: What’s the difference between a root, base word, and stem? The reason teachers are forced to debate this question is that their textbooks present a model that quickly falls apart in the real world.

If teachers are confused, their students will also be confused. By the end of this page, you won’t be confused. To end this confusion, we will look at two systems:

1. The Traditional Root and Base-Word System for Kids
2. A Modern System of Morphemes, Roots, Bases, and Stems from Linguistics

The Traditional Root and Base-Word System for Kids

Here is a problem-filled system that, unfortunately, some students still learn.

Students learn that ROOTS are Greek and Latin roots. Most of these roots cannot stand alone as words when we remove the prefixes and suffixes.

Q e.g., Word: justify      Latin Root: jus (law)

Students also learn that BASE WORDS can stand alone as words when we remove all of the prefixes and suffixes. Students learn that if it cannot stand alone when we remove all of the prefixes and suffixes, then it is not a base word.

Q e.g., Word: kindness      Base Word: kind

The problem comes later in the day when the teacher is teaching verb tenses.

Q Teacher: Look at these two verbs: responded and responding. What’s the base word?

Q Student #1: Respond.

Q Teacher: Correct!

Q Student #2: Isn’t re- a prefix? If re- is a prefix, then respond can’t be a base word. I suspect that spond is a Latin root. Is it?

Q Teacher: I’m not sure. Let me research this. Yes, the word respond has the prefix re- attached to the Latin root spond. The Latin root spond comes from sponder, which means to pledge.

Although the teacher was looking for the answer “respond,” Student #2’s answer was the correct answer according to this Traditional System. That’s how easily the Traditional System falls apart. And the problems get worse from here.

Modern Linguistics

I looked at a few current student textbooks from major publishers, and most of them don’t mention the terms base or base word. They only use the term root in their basic word studies. I suspect that this is because modern linguistics has created a new meaning for the term base.

In case you are not aware, modern linguistics and modern grammar fix many of the broken models from centuries past—i.e., models and definitions that quickly fall apart when you question them. These days, most books on linguistics and morphology present a somewhat standardized model. In English Word-Formation (1983), Laurie Bauer explains this model succinctly and definitively. Let’s take a look.

English Word-Formation (1983) by Laurie Bauer

As you can see below, Bauer acknowledges the root/stem/base problem and then explains a model that removes the ambiguity.

The Problem: “‘Root’, ‘stem’ and ‘base’ are all terms used in the literature to designate that part of a word that remains when all affixes have been removed. Of more recent years, however, there has been some attempt to distinguish consistently between these three terms.”

Root: “A root is a form which is not further analysable, either in terms of derivational or inflectional morphology. It is that part of word-form that remains when all inflectional and derivational affixes have been removed… In the form ‘untouchables’ the root is ‘touch’.”

Stem: “A stem is of concern only when dealing with inflectional morphology. In the form ‘untouchables’ the stem is ‘untouchable’.” [In short, when you remove the inflectional suffixes, you have the stem.]

Base: “A base is any form to which affixes of any kind can be added. This means that any root or any stem can be termed a base… ‘touchable’ can act as a base for prefixation to give ‘untouchable’.”

This model holds up across the curriculum. This model is the foundation of what I teach my students.

My Perfect Model: Roots, Stems, and Bases

I always like to have a complete model in mind that holds up across the curriculum. This lets me find teaching moments and ensures that I can answer my students’ questions clearly and consistently. Although I may not teach my students the entire model, at least the concepts are straight in my mind.

For this reason, I created this “Perfect Model of Roots, Stems, and Bases.” To be clear, this model is an interpretation and fuller explanation of what you might find in a linguistics book. Let me explain it to you. It all begins with morphemes.

Keep in mind that teachers don’t need to teach their students this entire model. In fact, most teachers will want to keep their morphology lessons simple and focus on roots, prefixes, and suffixes. But all teachers will want to understand this entire model.

Morphemes

The term morpheme unifies the concepts of roots, prefixes, and suffixes, and therefore, it is an extremely valuable word. In short, words are composed of parts called morphemes, and each morpheme contributes meaning to the word. Morphemes are the smallest unit of language that contains meaning. Roots, prefixes, and suffixes all have one thing in common—they are all single morphemes. In contrast, stems and bases can be composed of one or many morphemes.

Root / Root Morpheme

When I use the term root, I always mean the root morpheme. The root is always the main morpheme that carries the main meaning of a word. Since a morpheme is the smallest unit of language that contains meaning, we can’t divide or analyze the root morpheme any further. Although a root can be a stand-alone word, to avoid confusion, I never use the term “root word.” I use the term root, and I use the term root morpheme to reinforce what a root is.

We have two types of root morphemes:

1. Dependent (bound) Roots: These roots cannot stand alone as words. These roots are usually Greek and Latin roots. Here are a few examples:

    • liberty          root: liber (free)
    • interrupt         root: rupt (break)
    • similar         root: sim (like)

2. Independent (free) Roots: These roots are stand-alone words. Practically speaking, these roots are almost always single-syllable words. You know the ones. It seems to me that most multi-syllable words can be further divided and further analyzed. With a little research, one finds that an ancient prefix or suffix has merged with a root. In short, most multi-syllable words are not root morphemes.

Here is what they thought 150 years ago. Although modern linguistics does not agree with these statements, it’s still food for thought. My point is that most of the independent roots that we deal with inside of the classroom are single-syllable words.

Q “All languages are formed from roots of one syllable.” – New Englander Magazine (1862)

Q “All words of all languages can be reduced to one-syllable roots.” – New Jerusalem Magazine (1853)

Here are a few examples:

    • replaced          root: place
    • mindfulness         root: mind
    • carefully         root: care

The Terms: Dependent Root and Independent Root

Modern linguistics use the term bound (for dependent) and free (for independent) to classify morphemes. Since teachers spend so much time teaching students about dependent clauses and independent clauses, I transfer this knowledge and terminology over to morphemes. Put simply: independent morphemes CAN stand alone; dependent morphemes CAN’T stand alone.

Q PREFIXES and SUFFIXES are almost always dependent morphemes—i.e., they can’t stand alone as words.

Q ROOTS are either dependent or independent morphemes.

Now, we will examine words that contain one root and words that contain two roots. As you examine these words, pay special attention to the dependent root and independent root aspect.

One Root: Many words have just one root. That one root may be a Dependent Root or an Independent Root. Remember, the root carries the main meaning of the word.

Q Word: justify             Dependent Root: jus

Q Word: kindness           Independent Root: kind

Two Roots: Some words have two roots. The roots may be Dependent Roots or Independent Roots. With two roots, each root contributes near equal meaning to the word.

Two Dependent Roots

Q Word: geography       Dependent Root: geo (earth)    Root: graph (write)

Q Word: carnivore   Dependent Root: carn (flesh)   Dependent Root: vor (swallow)

Q Word: cardiovascular   Dependent Root: cardi (heart)    Dependent Root: vas (vessel)

Two Independent Roots

Q Word: bathroom    Independent Root: bath    Independent Root: room

Q Word: downfall    Independent Root: down    Independent Root: fall

Q Word: popcorn    Independent Root: pop    Independent Root: corn

pencil and paper Pattern Based Writing: Quick & Easy Essay! Put simply, it works.

Stem

I use the term stem just as Bauer does. To find the stem, simply remove the inflectional suffixes. It’s that simple.

When to Use the Term Stem: The term stem is quite unnecessary in many classrooms, as all stems are bases. For this reason, teachers can always use the term base instead of stem. However, the concept of stems is helpful in teaching students about inflectional suffixes. Inflectional suffixes are different from derivational affixes (derivational prefixes and derivational suffixes).

Q Word: reddest    Stem: red

Q Word: girls’    Stem: girl

Q Word: boats    Stem: boat

Q Word: preapproved    Stem: preapprove

Q Word: justifying    Stem: justify

Q Word: responded   Stem: respond

Q Word: unjustifiable    Stem: no stem

Q Word: kindness    Stem: no stem

Base / Base Word

Bauer says, “A base is any form to which affixes of any kind can be added. This means that any root or any stem can be termed a base.”

In the table below, I use two labels to show how base and root relate to each other. Sometimes a base is a root (marked   Q Base/Root), and sometimes it is not a root (marked   Q Base).

To be clear, we can add a prefix or suffix to every base even if it already has a prefix or suffix. Furthermore, if we can add a prefix or suffix to something, we can call it a base.

Word: reread    Q Base/Root: read

Word: unhelpful    Q Base: helpful    Q Base/Root: help

Word: justifying    Q Base: justify    Q Base/Root: jus

Word: unreliable    Q Base: reliable    Q Base/Root: rely

Word: preponderance    Q Base: ponderance (uncommon)    Q Base/Root: ponder

Word: responded    Q Base: respond    Q Base/Root: spond

Word: preapproved    Q Base: preapprove    Q Base: approve    Q Base: approved    Q Base: proved    Q Base/Root: prove

Base vs. Base Word: To keep things simple, teachers should probably strike the term “base word” from their vocabulary. However, if the base is a complete word that can stand alone, teachers may choose to (or through force of habit) refer to it as a base word. If the base can’t stand alone, be sure not to call it a base word.

When to Use the Term Base: The term base is somewhat of a generic term for when we are not interested in or concerned with the root morpheme. As an example, we may choose to use the term base when we are ADDING prefixes and suffixes. When we are adding prefixes and suffixes, we often are unconcerned with finding or discussing the root morpheme. (Remember, we often add prefixes and suffixes to words that already contain prefixes and suffixes.) We may also choose to use the term base when removing a single, specific prefix or suffix, as the word may still contain other prefixes or suffixes.

Putting It All Together

Here is a table to help get you started in your word analysis studies related to root, stem, and base.

Example Word Stem Root: Dependent Root: Independent Base
1. undeniable  deny ** deny; deniable
2. reinvented reinvent ven/vent ven/vent; invent; reinvent
3. deforestation forest *** forest; forestation
4. interacted interact act * act; interact
5. demographics demographic demo graph * demo; graph; demographic
6. responding respond spond spond; respond
7. preserving preserve serv serv; preserve
8. hopefully hope hope; hopeful

The Asterisks: The asterisks may be the most important part of this table. They help illustrate that every word has a unique history that often makes analysis and classification complicated and debatable.

* act and graph are also Latin roots

** deny is from Latin denegare = de (away) + negare (to refuse; to say no); since deny technically
has a Latin prefix (de-), you may choose to classify the word differently.

*** forest is from Latin foris meaning outdoors, and unlike the word deny, cannot be analyzed as
having a prefix or suffix attached.

Types of Word Formation Processes

Compounding
Compounding forms a word out of two or more root morphemes. The words
are called compounds or compound words.

In Linguistics, compounds can be either native or borrowed.

Native English roots are
typically free morphemes, so that means native compounds are made out of
independent words that can occur by themselves. Examples:

mailman (composed of free root mail and free root man)
mail carrier
dog house
fireplace
fireplug (a regional word for ‘fire hydrant’)
fire hydrant
dry run
cupcake
cup holder
email
e-ticket
pick-up truck
talking-to

Some compounds have a preposition as one of the component words as in the
last 2 examples.

In Greek and Latin, in contrast to English, roots do not typically stand
alone. So compounds are composed of bound roots. Compounds formed in
English from borrowed Latin and Greek morphemes preserve this
characteristic. Examples include photograph,
iatrogenic, and many thousands of other classical words.

Note that compounds are written in various ways in English:
with a space between the elements; with a hyphen between the
elements; or simply with the two roots run together with no separation.
The way the word is written does not affect its status as a
compound. Over time, the convention for writing compounds can change,
usually in the direction from separate words (e.g. email used to be written with a hyphen.
In the 19th century, today and tomorrow were sometimes still written to-day and to-morrow. The to originally was the preposition to with an older meaning ‘at [a particular period of time]’.
Clock work changed
to clock-work and finally to one word with no break
(clockwork). If you read older literature you might see some
compound words that are now written as one word appearing
with unfamiliar spaces or hyphens between the components.

Another thing to note about compounds is that they can combine words
of different parts of speech. The list above shows mostly noun-noun
compounds, which is probably the most common part of speech
combination, but there are others, such as adjective-noun (dry
run
, blackbird, hard drive), verb-noun (pick-pocket,
cut-purse, lick-spittle) and even verb-particle (where
‘particle’ means a word basically designating spatial expression that
functions to complete a literal or metaphorical path), as in
run-through, hold-over. Sometimes these compounds are
different in the part of speech of the whole compound vs. the part of
speech of its components. Note that the last two are actually nouns,
despite their components.

Some compounds have more than two component words. These are formed
by successively combining words into compounds, e.g. pick-up truck,
formed from pick-up and truck , where the first component,
pick-up is itself a compound formed from
pick and up. Other examples are ice-cream
cone
, no-fault insurance and even more complex compounds like
top-rack dishwasher safe.

There are a number of subtypes of compounds that do not have to do
with part of speech, but rather the sound characteristics of the
words. These subtypes are not mutually exclusive.

Rhyming compounds (subtype of compounds)
These words are compounded from two rhyming words. Examples:

lovey-dovey
chiller-killer

There are words that are formally very similar to rhyming compounds,
but are not quite compounds in English because the second element is
not really a word—it is just a nonsense item added to a root word to
form a rhyme. Examples:

higgledy-piggledy
tootsie-wootsie

This formation
process is associated in English with child talk (and talk addressed
to children), technically called hypocoristic language. Examples:

bunnie-wunnie
Henny Penny
snuggly-wuggly
Georgie Porgie
Piggie-Wiggie

Another word type that looks a bit like rhyming compounds
comprises words that are formed of
two elements that almost match, but differ in their vowels.
Again, the second element is typically a nonsense form:

pitter-patter
zigzag
tick-tock

riffraff
flipflop

Derivation
Derivation is the creation of words by modification of a root without
the addition of other roots. Often the effect is a change in part of
speech.

Affixation (Subtype of Derivation)
The most common type of derivation is the addition of one or more affixes to a
root, as in the word derivation itself. This process is called
affixation, a term which covers both prefixation and suffixation.

Blending
Blending is one of the most beloved of word formation processes in
English. It is especially creative in that speakers take two words
and merge them based not on morpheme structure but on sound structure.
The resulting words are called blends.

Usually in word formation we combine roots or affixes along their
edges: one morpheme comes to an end before the next one starts. For example, we
form derivation out of the sequence of morphemes
de+riv+at(e)+ion. One morpheme follows the next and each one has
identifiable
boundaries. The morphemes do not overlap.

But in
blending, part of one word is stitched onto another word, without any
regard for where one morpheme ends and another begins. For example,
the word swooshtika ‘Nike swoosh as a logo symbolizing
corporate power and hegemony’
was formed from swoosh and swastika. The swoosh
part remains whole and recognizable in the blend, but the tika part is
not a morpheme, either in the word swastika or
in the blend. The blend is a perfect merger of form, and also of
content. The meaning contains an implicit analogy between the
swastika and the swoosh, and thus conceptually blends them into one
new kind of thing having properties of both, but also combined
properties of neither source. Other examples include glitterati (blending
glitter and literati) ‘Hollywood social set’, mockumentary (mock and
documentary) ‘spoof documentary’.

The earliest blends in English only go back to the 19th century, with
wordplay coinages by Lewis Carroll in Jabberwocky. For example, he
introduced to the language slithy, formed from lithe and
slimy, and galumph, (from gallop and
triumph. Interestingly galumph has survived as a word in
English, but it now seems to mean ‘walk in a stomping, ungainly way’.

Some blends that have been around for quite a while include brunch
(breakfast and lunch), motel (motor hotel), electrocute (electric and
execute), smog (smoke and
fog) and cheeseburger (cheese and hamburger).
These go back to the first half of the twentieth
century. Others, such as stagflation (stagnation and inflation),
spork (spoon and fork), and carjacking (car and hijacking) arose
since the 1970s.

Here are some more recent blends I have run across:

mocktail (mock and cocktail) ‘cocktail with no alcohol’
splog (spam and blog) ‘fake blog designed to attract hits and
raise Google-ranking’
Britpoperati (Britpop and literati) ‘those knowledgable about current British pop music’

Clipping
Clipping is a type of abbreviation of a word in which one part is
‘clipped’ off the rest, and the remaining word now means essentially the same
thing as what the whole word means or meant. For example, the word
rifle is a fairly modern clipping of an earlier compound
rifle gun, meaning a gun with a rifled barrel. (Rifled means
having a spiral groove causing the bullet to spin, and thus making it
more accurate.) Another clipping is burger, formed by clipping
off the beginning of the word hamburger. (This clipping could
only come about once hamburg+er was reanalyzed as ham+burger.)

Acronyms

Acronyms are formed by taking the initial letters of a phrase
and making a word out of it. Acronyms provide a way of turning a phrase into a word. The classical acronym is also
pronounced as a word. Scuba was formed
from self-contained underwater breathing apparatus. The
word snafu was originally WW2 army slang for Situation
Normal All Fucked Up. Acronyms were being used more and more by
military bureaucrats, and soldiers coined snafu in an
apparent parody of this overused device. Sometimes an acronym uses not just the first letter, but the first syllable of a component word, for example radar, RAdio Detection And Ranging and sonar, SOund Navigation and Ranging. Radar forms an analogical model for both sonar and lidar, a technology that measures distance to a target and and maps its surface by
bouncing a laser off it. There is some evidence that lidar was not coined as an acronym, but instead as a blend of light and radar. Based on the word itself, either etymology appears to work, so many speakers assume that lidar is an acronym rather than a blend.

A German example that strings together the initial syllables of the
words in the phrase, is Gestapo , from GEheime STAats POlizei
‘Sectret State Police’. Another is Stasi, from STAats
SIcherheit ‘State Security’.

Acronyms are a subtype of initialism. Initialisms also include words made from the initial letters of a Phrase but NOT pronounced as a normal word — it is instead pronounced as a string of letters. Organzation names aroften initialisms of his type. Examples:

NOW (National Organization of Women)
US or U.S., USA or U.S.A. (United States)
UN or U.N. (United Nations)
IMF (International Monetary Fund)

Some organizations ARE pronounced as a word:
UNICEF
MADD (Mothers Against Drunk Driving)

The last example incorporates a meaning into the word that fits the nature of the organization. Sometimes this type is called a Reverse Acronym or a Backronym.

These can be thought of as a special case of acronyms.

Memos, email, and text messaging (text-speak) are modes of communication
that give rise to both clippings and acronyms, since these
word formation methods are designed to abbreviate.
Some acronyms:

NB — Nota bene, literally ‘note well’. Used by scholars making notes
on texts. (A large number of other scholarly acronyms from Latin are
used, probably most invented in the medieval period or Renaissance,
not originally in Latin)
BRB — be right back (from 1980s, 90s)
FYI — for your information (from mid 20th century)

LOL — laughing
out loud (early 21st century) — now pronounced either /lol/ or /el o
el/; has spawned compounds like Lolcats).
ROFL — rolling on the floor laughing
ROFLMAO — rolling on the floor laughing my ass off

Reanalysis
Sometimes speakers unconsciously change the morphological boundaries of a word, creating a new morph or making an old one unrecognizable. This happened in hamburger, which was originally Hamburger steak ‘chopped and formed steak in the Hamburg style, then hamburger (hamburg + er), then ham + burger

Folk etymology
A popular idea of a word’s origin that is not in accordance with its real origin.

Many folk etymologies are cases of reanalysis in which the word is not only reanalysis but it changes under the influence of the new understanding of its morphemes. The result is that speakers think it has a different origin than it does.

Analogy
Sometimes speakers take an existing word as a model and form other words using some of its morphemes as a fixed part, and changing one of them to something new, with an analogically similar meaning. Cheeseburger was formed on the analogy of hamburger, replacing a perceived morpheme ham with cheese.
carjack and skyjack were also formed by analogy.

Novel creation
In novel creation, a speaker or writer forms a word without starting
from other morphemes. It is as if the word if formed out of ‘whole
cloth’, without reusing any parts.

Some examples of now-conventionalized words that were novel creations
include blimp, googol (the mathematical term),
bling, and possibly slang, which emerged in the last 200
years with no obvious etymology. Some novel creations seem to display
‘sound symbolism’, in which a word’s phonological form suggests its
meaning in some way. For example, the sound of the word bling
seems to evoke heavy jewelry making noise. Another novel creation whose sound seems
to relate to its meaning is badonkadonk, ‘female rear end’, a
reduplicated word which can remind English speakers of the repetitive
movement of the rear end while walking.

Creative respelling
Sometimes words are formed by simply changing the spelling of a word
that the speaker wants to relate to the new word. Product names
often involve creative respelling, such as Mr. Kleen.

How are words formed? Are there any rules by which words are formed? Let’s find out. This article will walk you through what word formation is, the various types of word formation and the rules to be adhered to when forming words. The number of examples given will make your learning process more effective and easier. Check it out.

The English language is known for its wonderful quality of the way in which words and sentences are formed and used. Formation of new words from an existing root word by adding a syllable or another word is the general process; however, there are multiple ways in which it can be done.

Types of Word Formation with Examples

The formation of words is classified into four types based on how the process of formation is carried out. They are:

  • By adding prefixes
  • By adding suffixes
  • Converting from one word class to another
  • Forming compound words

Let us look at each type of word formation in detail.

Adding Prefixes

The term ‘prefix’ refers to one or more alphabets added to the stem of a word, mostly to make it negative. The most commonly used prefixes include ‘in-’, ‘un-’, ‘dis-’, ‘im-’, ‘ir-’, etc. Look at the examples given below for a clearer understanding of how prefixes are used to form new words.

Examples of Word Formation by the Addition of Prefixes

  • Discipline – indiscipline
  • Just – unjust
  • Tidy – untidy
  • Respect – disrespect
  • Understand – misunderstand
  • Comfortable – uncomfortable
  • Comfort – discomfort
  • Responsible – irresponsible
  • Honest – dishonest
  • Happy – unhappy
  • Polite – impolite
  • Experience – inexperience
  • Practical – impractical
  • Important – unimportant
  • Legal – illegal
  • Ethical – unethical
  • Potent – impotent

Adding Suffixes

A suffix is a short syllable added at the end of a base word. The addition of suffixes usually changes the word class of the particular word. The most common suffixes include ‘-ment’, ‘-ness’, ‘-ity’, ‘-ous’, ‘-tion’, ‘-sion’, ‘-al’, ‘-able’, ‘-ible’, ‘-ive’, ‘-ly’, ‘-ate’, ‘-er’, ‘-or’, etc. Check out the following examples to see how suffixes are added.

Examples of Word Formation by the Addition of Suffixes

  • Comprehend (verb) – comprehension (noun) – comprehensible (adjective)
  • Inform (verb) – information (noun) – informative (adjective)
  • Invest (verb) – Investment (noun) – Investor (noun)
  • Write (verb) – writer (noun)
  • Authorise (verb) – authorisation (noun)
  • Move (verb) – movement (noun)
  • Add (verb) – addition (noun)
  • Happy (adjective) – happiness (noun)
  • Conserve (verb) – conservation (noun)
  • Wide (Adjective) – widen (verb)
  • Manage (verb) – manageable (adjective) – manager (noun)
  • Courage (noun) – courageous (adjective)
  • Brave (adjective) – bravery (noun)
  • Profit (noun) – profitable (adjective)
  • Quick (adjective) – quickly (adverb)
  • Happy (adjective) – happily (adverb)
  • Sad (adjective) – sadness (noun)

Conversion

The process of conversion focuses solely on changing the word class of the particular word. If you have noticed, you would have seen how some nouns are used to perform the role of a verb or an adjective acting like a noun just by the addition of another word or slightly altering the spelling of the actual word.

Examples of Word Formation by Conversion

  • The rich should help the poor.

Adjectives such as ‘rich’ and ‘poor’ are used as nouns by using them with the article ‘the’.

  • Everyone is talented.

‘Talented’ – a past participle is used as an adjective in the above sentence. The word is formed by adding the suffix ‘ed’ to the end of the noun ‘talent’.

  • There will definitely be a lot of ups and downs in life.

Prepositions ‘up’ and ‘down’ are used as nouns by adding ‘s’ to the end of it.

  • He texted me about the meeting only at the last minute.

The noun ‘text’ used to refer to a text message sent on a phone is used as a verb in the sentence by adding an ‘ed’ to the end of the word.

  • The financial aid had to be approved before we could make a decision.

The noun ‘finance’ is used as an adjective by adding ‘ial’ to the end of it and the verb ‘decide’ is used as a noun by removing ‘de’ and adding ‘sion’ to the word.

Forming Compound Words

Compound words are formed by combining one part of speech with another to form a specific word class. There are many ways in which compound words are formed. Verbs are combined with adjectives to form compound verbs, a present participle is combined with a noun to form a compound noun, two nouns are combined to form a compound noun, an adjective and a noun are combined to form a compound noun, an adverb is combined with a noun to form a compound noun, an adjective is combined with a past participle to form a compound adjective and so on. Take a look at the following examples and go through the articles on compound nouns, compound words and compound adjectives to understand how they work.

Examples of Word Formation by Compounding

  • Over (adverb) + load (noun) – Overload
  • White (adjective) + wash (verb) – Whitewash
  • Black (adjective) + board (noun ) – Blackboard
  • Cup (noun) + board (noun) – Cupboard
  • Short (adjective) + hand (noun) – Shorthand
  • Swimming (present participle) + pool (noun) – Swimming pool
  • Three (adjective) + legged (past participle) – Three-legged
  • Break (verb) + Down (preposition) – Breakdown
  • Up (preposition) + town (noun) – Uptown
  • Copy (verb) + writer (noun) – Copywriter
  • Sun (noun) + rise (verb) – Sunrise
  • Count (verb) + down (preposition) – Countdown
  • Flash (verb) + mob (noun) – Flash mob
  • Master (noun) + piece (noun) – Masterpiece
  • Round (adjective) + table (noun) – Round-table

Rules to be Followed When Forming Words

Formation of words can be a very interesting exercise, but you have to be really careful when you are adding inflections or affixes. There are a few things you will need to bear in mind when you are forming words. Take a look at the following points to learn what they are.

  • Before making any change to the stem of the word, try to analyse what is the kind of meaning you want the word to convey and what role the word will have to play in the sentence.
  • In most cases, the beginning of the base word remains the same. Only when prefixes are added the word has a syllable added to the beginning of it. Notice that even in this case, the word is retained as such.
  • When suffixes are added, there are many instances where you will have to remove the last one or more alphabets of the word and add the suffix. However, there are words like ‘movement’ where the suffix is just added without any change in the spelling of the base word.
  • Here is one way to easily know which suffix has to be added to form a particular word class – most often, nouns end in ‘er’, ‘or’, ‘ist’, ‘ian’, ‘ion’, ‘ment’, ‘ness’, and ‘ity’; verbs end in ‘ise’, ‘ate’ and ‘en’; adjectives end in ‘able’, ‘ible’, ‘ive’, ‘ic’, ‘ed’, ‘ing’ and ‘al’; and adverbs normally end in ‘ly’.
  • When words are formed by conversion, be very careful. Make sure you know that you are converting them accurately and using them in the sentence properly.
  • When forming compound words, see to it that you hyphenate them if necessary, use the right combination of words and do not just mix and match any word.
  • Changing from one tense to another also can also be considered a type of word formation, as the word is inflected to indicate the twelve different tenses in the English language.
  • Forming degrees of comparison can also be put under word formation. In this case, the comparative and superlative degrees are formed by adding ‘er’ and ‘est’ to the end of the adjective. The comparative and superlative degrees of polysyllabic words are formed by using ‘more’ and ‘most’, respectively, along with the adjective.
