Frequently asked questions:

• Which words in english contains root?
• What are the words having root in between?
• List of all those words in english having root anywhere in middle or on ends.

According
to the number of morphemes words are classified into monomorphic
and polymorphic.

Monomorphic
or
root-words consist of only one root-morpheme, e.g., small,
dog, make, give, etc.
All polymorphic
words according to the number of root-morphemes are classified into
two subgroups: monoradical or root words and polyradical words, i.e.,
words which consist of two or more roots.

Monoradical
words fall into two subtypes: 1) radical-suffixal
words, i.e., words that consist of one root-morpheme and one or more
suffixal morphemes, e.g., acceptable,
acceptability, blackish; 2)
radical-prefixal
words, i.e., words that consist of one root-morpheme and a prefixal
morpheme, e.g. outdo,
rearrange, unbutton; and
3) prefixo-radical-suffixal,
i.e., words which consist of one root, a prefixal and suffixal
morphemes, e.g., disagreeable,
misinterpretation.

Polyradical
words
fall into two subtypes: 1) polyradical words which consist of two or
more roots with no affixational morphemes, e.g., book-stand,
eye-ball,
lamp-shade; and
2) words which contain at least two roots and one or more
affixational morphemes, e.g., safety-pin,
wedding-pie, class-
consciousness,
light-mindedness, pen-holder.

1. Derivational and morphemic levels of analysis

The
morphemic
analysis
of words only defines the constituent morphemes, determining their
types and their meaning but does not reveal the hierarchy of the
morphemes comprising the word.

Morphemes
are arranged according to certain rules, the arrangement differing in
various types of words and particular groups within the same types.
The pattern of morpheme arrangement underlies the classification of
words into different types and enables one to understand how new
words appear in the language. These relations within the word and the
interrelations between different types and classes of words are known
as derivative
or word- formation relations.

The
analysis of derivative relations aims at establishing a correlation
between different types and the structural patterns words are built
on. The basic unit at the derivational level is the stem.The stem is
defined as that part of the word which remains unchanged throughout
its paradigm, thus the stem which appears in the paradigm (to) ask (
), asks,
asked, asking is ask-; thestem
of the word singer (
), singer’s,
singers, singers’ is singer-.

   word classification

1. Word
   formation in Modern English

Word
formation is a branch of science of the language which studies the
patterns on which a language forms new lexical items (new unities,
new words). Word formation is a process of forming words by
combining root
& affixal morphemes.

Different
types of word formation:

—
COMPOUNDING is joining together 2 or more stems.
Types: 1) without
a connecting element (headache, heartbreak); 2) with a vowel or
consonant as a linking element (speedometer, craftsman); 3) with a
preposition or conjunction as a linking element down-and-out
(опустошенный)
son-in-law.
— PREFIXATION Prefixes are such particles that can be
prefixed to full words. But are themselves not with independent
existence.
— SUFFIXATION A suffix is a derivative final element
which is or was productive in forming new words. It has semantic
value, but doesn’t occur as an independent speech use.
—
CONVERSION (zero derivation) A certain stem is used for the formation
of a categorically different word without a derivative element being
added.(Bag – to bag)
— BACK DERIVATION is deraving a new word,
which is morphologically simpler from a more complex word.  ( A
babysitter – to babysit     Television – to
televise)
— PHONETIC SYMBOLISM is using characteristic speech
sounds for name giving. Very often we imitate by the speech sounds
what we hear: (tinkle, splash, t).
— CLIPPING Consists in the
reduction of a word to one of its parts.     (
Mathematics – maths)
— BLENDING is blending part of two words to
form one word  ( Smoke + fog = smog)

1. Morphological
   structure of a word. Productive and non-productive ways of word
   formation.

Morphology
is the study of the structure and form of words in language or a
language, including inflection, derivation, and the formation of
compounds. At the basic level, words are made of «morphemes.»
These are the smallest units of meaning: roots and affixes (prefixes
and suffixes). Native speakers recognize the morphemes as
grammatically significant or meaningful. For example, «schoolyard»
is made of «school» + «yard», «makes»
is made of «make» + a grammatical suffix «-s»,
and «unhappiness» is made of «happy» with a
prefix «un-» and a suffix «-ness».

Inflection
occurs when a word has different forms but essentially the same
meaning, and there is only a grammatical difference between them: for
example, «make» and «makes». The «-s»
is an inflectional morpheme.

In
contrast, derivation makes a word with a clearly different meaning:
such as «unhappy» or «happiness», both from
«happy». The «un-» and «-ness» are
derivational morphemes. Normally a dictionary would list derived
words, but there is no need to list «makes» in a dictionary
as well as «make.»

Word-formation
is the process of creating new words from the material available in
the word-stock according to certain structural and semantic patterns
specific for the given language. There are different ways of
word-formation in Modern English. Some of them are highly-productive.
They are: affixation, conversion, substantivation, compounding,
shortening, formation of phrasal verbs. Others are semi-productive
(back-formation, blending, reduplication, lexicalization of the
plural of nouns, sound imitation) and non-productive ways of
word-building (sound interchange, change of stress).

Non-productive
ways of word-building Sound interchange (gradation) is the process in
which word belonging to different parts of speech may be
differentiated due to the sound interchange in the root, eg food (n)
:: feed (v), gold (n) :: gild (v), sing (v) :: song (n) .Change of
stress is mostly observed in verb-noun pairs, eg transport> to
transport and much more seldom in verb-adjective pairs, to prostrate>
prostrate. The difference in stress often appeared after the verb was
formed and was not therefore connected with the formation of the new
word.

Words can be puzzling for students as they are often pieced together by many different word parts (morphemes). A single word might contain a prefix, a suffix, root, and a base or root word, each part holding important information. A root word can be defined as a basic standalone word in which affixes can be added to create new words. A root is the basis of a word and it typically does not stand alone. Teaching root words to kids can help increase students’ proficiency at identifying roots and forming complete words.

It is essential to start teaching root words to kids early so students can develop an understanding of root words, roots, and other morphemes in order to deconstruct words and build word meaning. Our root word spelling lists, used in conjunction with engaging root word games and exercises, are a great way to improve student understanding of how words are formed.

Morphemes, also referred to as word-part clues, are units of language that hold meaning, but cannot be broken down any further into smaller meaningful parts. Two basic types of morphemes exist: bound and free. Bound morphemes cannot stand alone and must be attached to other morphemes to form a word, acting as the building blocks of a word. Affixes (prefixes and suffixes) and Latin and Greek root words are bound morphemes. Free morphemes, on the other hand, can stand alone. Free morphemes include English root words, such as the root word “teach” in “teacher.” Two free morphemes can join to form a compound word, for example “dog” and “house” to form “doghouse.” Morphemes are imperative when teaching root words to kids, and our root words games, exercises, and word lists can help students master the puzzles of word creation.

Prefixes and suffixes can be added to a root word to form many new words and change word meaning. Often the term base word is used interchangeably with root word. When affixes are added to them, they serve as the anchor of the word because they hold the word’s principle meaning.

While there are many conflicting definitions of root words and base words, teachers need to keep in mind the importance of teaching these topics. Knowledge of morphemes, like word roots, helps with reading fluency, vocabulary development, and reading comprehension.
