In English grammar, a word class is a set of words that display the same formal properties, especially their inflections and distribution. The term «word class» is similar to the more traditional term, part of speech. It is also variously called grammatical category, lexical category, and syntactic category (although these terms are not wholly or universally synonymous).

The two major families of word classes are lexical (or open or form) classes (nouns, verbs, adjectives, adverbs) and function (or closed or structure) classes (determiners, particles, prepositions, and others).

Examples and Observations

• «When linguists began to look closely at English grammatical structure in the 1940s and 1950s, they encountered so many problems of identification and definition that the term part of speech soon fell out of favor, word class being introduced instead. Word classes are equivalent to parts of speech, but defined according to strict linguistic criteria.» (David Crystal, The Cambridge Encyclopedia of the English Language, 2nd ed. Cambridge University Press, 2003)
• «There is no single correct way of analyzing words into word classes…Grammarians disagree about the boundaries between the word classes (see gradience), and it is not always clear whether to lump subcategories together or to split them. For example, in some grammars…pronouns are classed as nouns, whereas in other frameworks…they are treated as a separate word class.» (Bas Aarts, Sylvia Chalker, Edmund Weiner, The Oxford Dictionary of English Grammar, 2nd ed. Oxford University Press, 2014)

Form Classes and Structure Classes

«[The] distinction between lexical and grammatical meaning determines the first division in our classification: form-class words and structure-class words. In general, the form classes provide the primary lexical content; the structure classes explain the grammatical or structural relationship. Think of the form-class words as the bricks of the language and the structure words as the mortar that holds them together.»

The form classes also known as content words or open classes include:

• Nouns
• Verbs
• Adjectives
• Adverbs

The structure classes, also known as function words or closed classes, include:

• Determiners
• Pronouns
• Auxiliaries
• Conjunctions
• Qualifiers
• Interrogatives
• Prepositions
• Expletives
• Particles

«Probably the most striking difference between the form classes and the structure classes is characterized by their numbers. Of the half million or more words in our language, the structure words—with some notable exceptions—can be counted in the hundreds. The form classes, however, are large, open classes; new nouns and verbs and adjectives and adverbs regularly enter the language as new technology and new ideas require them.» (Martha Kolln and Robert Funk, Understanding English Grammar. Allyn and Bacon, 1998)

One Word, Multiple Classes

«Items may belong to more than one class. In most instances, we can only assign a word to a word class when we encounter it in context. Looks is a verb in ‘It looks good,’ but a noun in ‘She has good looks‘; that is a conjunction in ‘I know that they are abroad,’ but a pronoun in ‘I know that‘ and a determiner in ‘I know that man’; one is a generic pronoun in ‘One must be careful not to offend them,’ but a numeral in ‘Give me one good reason.'» (Sidney Greenbaum, Oxford English Grammar. Oxford University Press, 1996)

Suffixes as Signals

«We recognize the class of a word by its use in context. Some words have suffixes (endings added to words to form new words) that help to signal the class they belong to. These suffixes are not necessarily sufficient in themselves to identify the class of a word. For example, -ly is a typical suffix for adverbs (slowly, proudly), but we also find this suffix in adjectives: cowardly, homely, manly. And we can sometimes convert words from one class to another even though they have suffixes that are typical of their original class: an engineer, to engineer; a negative response, a negative.» (Sidney Greenbaum and Gerald Nelson, An Introduction to English Grammar, 3rd ed. Pearson, 2009)

A Matter of Degree

«[N]ot all the members of a class will necessarily have all the identifying properties. Membership in a particular class is really a matter of degree. In this regard, grammar is not so different from the real world. There are prototypical sports like ‘football’ and not so sporty sports like ‘darts.’ There are exemplary mammals like ‘dogs’ and freakish ones like the ‘platypus.’ Similarly, there are good examples of verbs like watch and lousy examples like beware; exemplary nouns like chair that display all the features of a typical noun and some not so good ones like Kenny.» (Kersti Börjars and Kate Burridge, Introducing English Grammar, 2nd ed. Hodder, 2010)

Both
the traditional and the syntactico — distributional classifications
divide parts of speech into notional
and
functional.

Criteria
for differentiating:

1. the
   prominence of their lexical meaning

2. peculiarities
   of their combinability

3. ability
   to be substituted by a word of a more general meaning

4. ability
   to create/add new items

Notional
words

1. Complete
   nominative force

2. Self-dependent
   functions in a sentence

3. Can
   be used in isolation

4. Can
   be substituted by a word of a more general meaning

5. Open
   classes (new items can be added to them, they are indefinitely
   extendable)

Functional
words

1. Incomplete
   nominative force

2. Non-self-dependent
   mediatory functions:
   linking
   or specifying

3. Obligatory
   combinability

4. Cannot
   be substituted

5. Closed
   classes (closed
   systems, including a limited number of members. As a rule, they
   cannot be extended by creating new items)

The
main notional
parts of speech are nouns,
verbs, adjectives and adverbs. Members of these four classes are
often connected by derivational relations: strength
—
strengthen;-
strong —
strongly.

Functional
parts of speech are
prepositions, conjunctions, articles, particles.

Pronouns
constitute a class of words which takes an intermediary position
between notional and functional words. On the one hand, they can
substitute for nouns and adjectives, on the other hand, pronouns are
used as connectives and specifiers.

Groups
of functional words (function words — Ch. Fries)

• With
  a
  unilateral combinability
  – articles, auxiliaries, modals, particles

• With
  a
  bilateral combinability
  – prepositions and conjunctions which connect 2 or more notional
  words or word- groups

• Heterogeneous
  subclass
  uniting introductory it/there, interrogative words, interjections
  etc

There
may be also groups of closed-system items(functional words) within an
open class notional words)- e.g. notional,
functional and auxiliary verbs.

A
word in English is very often not marked morphologically and it is
easy for words to pass from one class to another (round
as
a noun, adjective, verb, preposition). Such words arc treated either
as lexico-grammatical homonyms or as words belonging to one class.

7.The noun. The category of number

Noun
as a part of speech:

1. Semantic
   – a part of speech which categorial meaning is thingness

2. Formal
   – a) form-building – the category of number, the category of
   case, the category of gender, the category of article determination

b)
derivational – typical word-building patterns: suffixation,
compounding, convertion (to walk – a walk)

3)
Functional – a) combinability: left-hand prepositional
combinability with another N/V/Adj./Adv. [+ prep.Noun],casal
combinability [N’s+N](
.:
the
speech of the President —
the
President’s speech),
contact comb-ty [N+N]- stone-wall constructions, take
an intermediary position between compound nouns and noun phrases
(stone wall, car roof, speech sound),
comb-ty with articles and other determiners [art./det. + N]

b)
Syntactic functions – subject, object, other functions are less
typical

Nouns
fall into several subclasses which differ as to their semantic and
grammatical properties: common — proper, concrete — abstract,
countable — uncountable (count — non-count, count — mass),
animate — inanimate, personal — non-personal (human —
non-human).

Lexico-
semantic variants of nouns may belong to different subclasses: paper
— a paper, etc.

The
class of nouns can be described as a lexico-grammatical field.
Nouns denoting things constitute the centre (nucleus) of the field.
Nouns denoting processes, qualities, abstract notions (predicate
nouns) are marginal, peripheral elements of the field.

• Nucleus
  and periphery are distinguished on the basis of lexico-semantic
  properties and morph. characteristics – subclasses of Nouns

• The
  nucleus -> common- concrete-countable- animate Nouns

• The
  periphery -> abstract – material- uncountable Nouns

The
category of number

The
only category of nouns, which is generally accepted, is the category
of number. Many scholars think that the notion of case applies to
English pronouns, but not to nouns. Gender distinctions are not
marked morphologically.

The
category of number
— is a semantically rooted morphological category ,

• depends
  on how the referent is perceived: as a discrete, hence countable
  entity, one or more than one, OR as an indiscrete indivisible, hence
  uncountable entity

• this
  semantic contrast is revealed through lexical and morphological
  means which are accompanied by syntactic marking

Lexical
( lexico-syntactic) means:

• The
  process of lexicalizing
  semantic contrast consists in denoting a discrete countable entity
  by one word – a meal and an indiscrete uncountable entity – by
  another – food.

We
made a journey – we made a travel

Lexico-
grammatical means:

-s
– news – singularia tantum, goods – pluralia tantum, marked
through syntactic
patterning – the
form of the predicate verb, use of articles and corresponding
pronouns

Lexicalization
of the plural form (the
process when a word requires a new name, a word already having a
meaning gets a new one)

Colours
— > flag, pains -.> efforts

Grammatical
means:

The
morph. Category of Number is realized through inflectional
marking (categorial
forms) and/or syntactic patterning

Form:
the category of Number is constituted by the inflectional opposition
of 2 categorial forms of Noun:

Non-pl.(sg.)
— Pl⁺
binary,
privative opposition

Dog⁻
dogs⁺
⁺
—a
strong marked member, marked through the inflexion, ⁻-
zero morpheme.

Sg.
– no positive mark, zero inflexion, a weak unmarked member, many
a river

Pl.
– morpheme of plurality – (e)s, represented by:

• the
  allomorphs ( variants of 1 morpheme) books
  (s), boys(z), boxes(iz)

• by
  some other allomorphs ex. oxen

• internal
  inflexion – sound interchange mouse-mice

• zero
  inflexion (NB! – only in grammar) – sheep,
  means

Meaning
of their category of Number and its members the
foundation
is laid by the opposition

Discreteness
– non- discreteness which
embraces countable and uncountable nouns

Discrete
counts
form the inflexional opposition

Non-pl.-
pl.
dog⁻-dogs⁺

Non-pl.
– a single object having distinct outer boundaries

Pl.
– a set of homogeneous objects having distinct inner and outer
boundaries

Indiscrete
uncounts
constitute the lexico-gram.
opposition of subclasses of nouns:

Sg.
Only – pl. only

Sg.
only –
indiscrete entities having no boundaries ->mainly abstract and
material uncounts

Pl.only
(see
pract. Grammar)

THE
CATEGORY OF NUMBER

Discreteness
Non-discreteness

morphological
c. lexico-gram.
subclass

Non-pl.(oneness)
Sg. only

—
a single discrete entity — indiscrete
entities, no boundaries

Pl.(more
–than- oneness) Pl. only

—
multiplicity of discrete entities <…>

Bloh
Pl only

The
characteristic of the uncountable nouns which denote objects
consisting of two halves
(trousers,
scissors, tongs, spectacles, etc.),
the
nouns expressing some sort of collective meaning,
i.e. rendering the idea of indefinite plurality, both concrete and
abstract (supplies,
outskirts, clothes, parings; tidings, earnings, contents, politics;
police, cattle, poultry, etc.),
the
nouns denoting some diseases as well as some abnormal states of the
body and mind
(measles,
rickets, mumps, creeps, hysterics, etc.).
As is seen from the examples, from the point of view of number as
such, the absolute plural forms can be divided into set absolute
plural (objects of two halves) and non-set absolute plural (the
rest).

Words are the building blocks in any sentence. They just don’t ‘mean’ something, they ‘do’ something in every sentence. Hence words are grouped into word classes based on what they do. A word class is a group of words that have certain common features. The term “word class” is analogous to the more conventional term, “part of speech.” It is also variously named grammatical category, lexical category, and syntactic category.

• Open and Closed Word Classes
• Open Word Classes
• Closed Word Classes

• How to classify a word class?
• What is the difference between a word class and part of speech?

Word classes can be divided into two families:

• Lexical Classes: Also known as open classes and form classes. The lexical classes include nouns, verbs, adjectives, and adverbs.
• Function Classes: Also known as closed classes and structure classes. Includes: pronouns, determiners, conjunctions, prepositions, and interjections.

Open and Closed Word Classes

As previously mentioned some word classes are open, that is, the class can be expanded with the addition of new words. Take the example of the class of nouns, it is potentially infinite as the number of words in the class is increasing as new scientific and technological discoveries are made.

The latter half of the twentieth century witnessed developments in computer technology which have in turn given rise to many new nouns like the Internet, URL website, bitmap, email, etc.

On the other hand, the word classes of prepositions, determiners, or conjunctions are known as closed word classes. Words like of, the, and but come under these. They are named closed word classes because they consist of a definite set of words. These classes never expand even though the words included in the class may change their spelling.

Open Word Classes

1) Nouns

This class includes words that you frequently use in everyday life. Nouns are most commonly understood as “naming” words, that is, it performs the function of naming “people, places or things”.

• A person – Boy, Girl, John, etc
• A thing- House, Dog, etc
• A place- China, America, etc

However, the use of nouns is not restricted to just names of people, places, or things. Nouns also denote abstract and intangible concepts such as an idea, quality, or state. Example: Danger, Happiness, Love, etc.

2) Verbs

The words that you use to describe an action are known as verbs. Hence verbs are generally known as “action” words. Have a look at the given example: Rahul rides a scooter. The verb in the above sentence denotes an action that Rahul performs which is the action of riding a scooter.

However, the idea of verbs as “action” words is somewhat restricted. Many verbs don’t stand for action at all as in the given instance: Rahul seems desperate. We cannot say that the verb ‘seems ‘ refer to an action.

3) Adverbs

In English, an adverb describes a word that alters the meaning of a verb, adjective, or another adverb. Adverbs in a sentence give you more information about the sentence. They are used to express how an action is fulfilled. Adverbs can broadly be categorized into Simple Adverbs, IInterrogative adverbs, and Relative Adverbs.

Remember:

• Most adverbs end with the common ending – ly.
• An adverb that modifies an adjective or another adverb usually goes before it.

4) Adjectives

Adjectives describe the quality of a noun. For example They stay in a beautiful house

The word beautiful indicates or refers to one of the attributes of the house that is described. Hence beautiful becomes the adjective in the above sentence.

A point to keep in mind: Some adjectives can be identified by their ending. Typical adjective endings include: able, al, ful, ic, etc.

Closed Word Classes

1) Determiners

You might have often noticed that nouns are preceded by words like the, a, or an. These words are known as Determiners. They suggest the type of reference that the noun has.

• The determiner ‘the’ is called a Definite Article. It can be placed both before singular and plural nouns. For example The Taxi, The taxis
• The determiner a or an is known as the Indefinite Article. It is used along with a singular noun. Example: A taxi

Apart from these, many other determiners express quantity. These include ‘al’, ‘both’, ‘many’ etc.

2) Conjunctions

These are used to express connections between different words.

Example: John and David are friends. And is used as a conjunction in the given sentence.
The most familiar conjunctions in English are: and, but, and or.

Conjunctions are further divided into two:

• Coordinating Conjunctions: These conjunctions connect elements of equal syntactic structure. Example: Paul and David study together.
• Subordinating Conjunctions: Connects elements of unequal syntactic structure. Example: I left early because I had an interview the next day.

3) Prepositions

Prepositions indicate the relation between different words. They occur before a noun, pronoun, or noun phrase and indicate a direction, time, place, location, and spatial relationship. Common prepositions include across, after, at, before, by, during, from, in, into, of, on, to, under, with, without, etc.

4) Pronouns

If we did not have the pronoun word families we would have to repeat a whole lot of nouns. A word that takes the position of a noun is named as a pronoun. Pronouns can be employed as a substitute for a noun.

• Pronouns are divided into 5 categories:
• Personal Pronouns: I, you, she, etc
• Demonstrative Pronouns: This, these, etc
• Possessive Pronouns: Yours, His, etc
• Interrogative Pronouns: Which, What, etc
• Reflexive Pronouns: Herself, Himself, etc.
• Reciprocal Pronouns: Each other
• Indefinite Pronouns: Few, Nobody, etc.
• Relative Pronouns: Which, Whom, etc.

5) Interjections

Short exclamations like Oh!, Ah! etc are known as Interjections. Even though they have no grammatical value, we often use them in daily speech. Interjections are primarily used to express emotions such as anger, surprise, etc. Given below are a few examples.

Well! That hurts
Hey! Don’t be so clumsy

Remember, an interjection is always followed by an exclamation mark.

FAQs on Word Classes

1. How to identify the word classes in a sentence?

A word class is a group of words that have certain common features. To find out the word classes within a sentence it is important that you familiarise yourself with the most common word classes in English. These include nouns, adjectives, verbs, adverbs, prepositions, etc.

2. How to classify a word class?

Word classes in English belong to two major categories. These are Open word classes that include nouns, verbs, adjectives, and adverbs. The second category is closed word classes that include: pronouns, determiners, interjections, etc.

3. What is the difference between a word class and part of speech?

The term “word class” is analogous to the more conventional term, “part of speech”. Both these terms refer to a group of words that have certain common features.

Conclusion

To understand the grammatical structures of sentences in a better way it’s best if you begin with word classes. Even though comprehending the different word classes may initially be a hectic task, once you master word classes, you will reach the exact meaning or message conveyed by a sentence.
