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)

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.

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.

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.

Every word in a sentence plays a different role, refer as the parts of speech. There are the following word classes in english grammar. Word Classes are very important part in grammar. They decide different rules of grammar. More precisely every grammar rule comes out of them. They are the most basic part of a sentences. Without word classes English language would never be possible and that why these 9 words classes are the base of English language.

The words
of language, depending on various formal and semantic features,
are divided into grammatically relevant sets or classes. The
tra­ditional grammatical classes of words are called «parts
of speech». Since the
word is distinguished not only by grammatical, but also by
semantico-lexemic properties, some scholars refer to parts of speech
as «lexico-grammatical»
series of words, or as «lexico-grammatical categories.

It
should be noted that the term «part of speech» is purely
traditional and
conventional, it cannot be taken as in any way defining or
explana­tory. This name was introduced in the grammatical
teaching of Ancient Greece, where the concept of the sentence was not
yet explicitly identi­fied
in distinction to the general idea of speech, and where,
consequently, no
strict differentiation was drawn between the word as a vocabulary
unit and the word as a functional element of the sentence.

In
modern linguistics, parts of speech are discriminated on the basis of
the three
criteria:
«semantic»,
«formal», and «functional».

The
se­mantic
criterion
presupposes the evaluation of the generalized meaning, which
is characteristic of all the subsets of words constituting a given
part of speech. This meaning is understood as the «categorial
meaning of
the part of speech».

The
formal criterion
provides for the exposition of the
specific inflexional and derivational (word-building) features of
allthe
lexemic subsets of a part of speech.

The
functional criterion
concerns the
syntactic role of words in the sentence typical of a part of speech.
The said
three factors of categorial characterization of words are
conven­tionally
referred to as, respectively, «meaning», «form»,
and «function».

In accord
with the described criteria, words on the upper level of
classification
are divided into notional
and functional,
which reflects their division
in the earlier grammatical tradition into changeable and
un­changeable.

To the
notional
parts of speech
of the English language belong the noun, the adjective, the numeral,
the pronoun, the verb, the adverb.

Contrasted against the
notional parts of speech are words of incom­plete nominative
meaning and non-self-dependent, mediatory functions in the sentence.
These are functional parts of speech.

To
the basic functional
series of words
in English belong the article, the
preposition, the conjunction, the particle, the modal word, the
inter­jection.

Each part of speech after its
identification is further subdivided into subseries in accord with
various particular semantico-functional and formal features of the
constituent words. This subdivision is some­times called
«subcategorization» of parts of speech.

Thus, nouns
are subcategorized into proper and common, ani­mate and
inanimate, countable and uncountable, concrete and ab­stract,
etc.

Verbs
are subcategorized into fully predicative and partially pred­icative,
transitive and intransitive, actional and statal, purely nomi­native
and evaluative, etc.

Adjectives
are subcategorized into qualitative and relative, of con­stant
feature and temporary feature (the latter are referred to as
«statives» and identified by some scholars as a separate
part of speech un­der the heading of «category of state»),
factual and evaluative, etc.

The adverb,
the numeral, the pronoun are also subject to the cor­responding
subcategorizations.

We have
drawn a general outline of the division of the lexicon into part
of speech classes developed by modern linguists on the lines of
tra­ditional
morphology.

Alongside
the three-criteria principle of dividing the words into grammatical
(lexico-grammatical) classes, modern linguistics has de­veloped
another, narrower principle
of word-class identification based on syntactic featuring of words
only.

The fact is
that the three-criteria principle faces a special difficulty in
determining the part of speech status of such lexemes as have
mor­phological characteristics of notional words, but are
essentially distin­guished from notional words by their playing
the role of grammatical mediators in phrases and sentences. Here
belong, for instance, modal verbs
together with their equivalents — suppletive fillers, auxiliary
verbs, aspective
verbs, intensifying adverbs, determiner pronouns. This diffi­culty,
consisting in the intersection of heterogeneous properties in the
established
word-classes, can evidently be overcome by recognizing only one
criterion of the three as decisive.

Comparing
the syntactico-distributional classification of words with the
traditional part of speech division of words, one cannot but see the
similarity of the general schemes of the two: the opposition of
notional and
functional words, the four absolutely cardinal classes of notional
words (since numerals and pronouns have no positional functions of
their
own and serve as pro-nounal and pro-adjectival elements), the
in­terpretation of functional words as syntactic mediators and
their formal representation
by the list.

However,
under these unquestionable traits of similarity are distinctly
revealed
essential features of difference, the proper evaluation of which
allows us to make some important generalizations about the structure
of the
lexemic system of language.

As
a result of the undertaken analysis
we have obtained a founda­tion
for dividing the whole of the lexicon at the upper level of
classifica­tion
into three unequal parts.

The
first part of the lexicon forming an open set includes an
indefi­nitely large number of notional words which have a
complete nomina­tive
function. In accord with the said function, these words can be re
ferred to as «names»: nouns as substance names, verbs as
process names, adjectives
as primary property names and adverbs as secondary proper­ty
names. The whole notional set is represented by the four-stage
deriva­tional
paradigm of nomination.

The
second part of the lexicon forming a closed set includes substi­tutes
of names (pro-names). Here belong pronouns, and also broad-mean­ing
notional words which constitute various marginal subsets.

The
third part of the lexicon also forming a closed set includes
spec­ifiers
of names. These are function-categorial words of various
servo-status.

Substitutes
of names (pro-names) and specifiers of names, while stand­ing
with the names in nominative correlation as elements of the lexicon,
at
the same time serve as connecting links between the names within the
lexicon
and their actual uses in the sentences of living speech.
