What Are Word Classes?

Word classes (also called parts of speech) are categories of words that share similar grammatical properties.
Words in the same class behave similarly in sentences: they play similar roles and often change form in similar ways.
Common English word classes include nouns, verbs, adjectives, adverbs, pronouns, prepositions, conjunctions, and determiners.
Some classes are open — they gain new members often (e.g. nouns, verbs, adjectives).
Other classes are closed — they rarely gain new members (e.g. pronouns, conjunctions).

Nouns

Nouns name people, places, things, or ideas.
Common nouns name general things (e.g.×city×,×dog×).
Proper nouns name specific people, places, or things and are capitalised (e.g.×London×,×Sarah×).
Abstract nouns name ideas, qualities, or states that you cannot see or touch (e.g.×freedom×,×happiness×).
Collective nouns name groups of people or things (e.g.×team×,×flock×).

Pronouns

Pronouns replace nouns or noun phrases to avoid repetition (e.g.×he×,×she×,×it×,×they×).
They can refer to people or things already mentioned or understood.
Pronouns are a closed class — new pronouns are rarely added to the language.

Verbs

Verbs express actions, events, or states of being (e.g.×run×,×think×,×is×).
Auxiliary verbs (helping verbs) are used with a main verb to form tenses, moods, or voices (e.g.×be×,×have×,×do×).
Modal verbs express possibility, necessity, ability, or permission (e.g.×can×,×must×,×should×).
Verbs change form to show tense, person, and number.

Adjectives

Adjectives describe or modify nouns and pronouns (e.g.×happy×,×red×,×large×).
They often answer questions like×What kind?×or×Which one?×.
Adjectives can be comparative (e.g.×bigger×) or superlative (e.g.×biggest×).

Adverbs

Adverbs modify verbs, adjectives, other adverbs, or whole clauses (e.g.×quickly×,×very×,×fortunately×).
They often answer questions like×How?×,×When?×,×Where?×, or×To what extent?×.
Many adverbs are formed by adding -ly to an adjective, but not all (e.g.×fast×,×well×).

Prepositions

Prepositions show relationships between a noun or pronoun and another word in the sentence (e.g.×in×,×on×,×at×,×by×,×with×).
They often indicate location, time, direction, or manner.
Prepositions are a closed class — new prepositions are rarely added.

Conjunctions

Conjunctions join words, phrases, or clauses together.
Coordinating conjunctions join items of equal grammatical rank (e.g.×and×,×but×,×or×).
Subordinating conjunctions introduce a subordinate clause and show its relationship to the main clause (e.g.×because×,×although×,×when×).
Conjunctions are a closed class.

Determiners

Determiners come before nouns to specify which one or how much (e.g.×the×,×a×,×this×,×some×,×my×).
They include articles (×a×,×an×,×the×), demonstratives (×this×,×that×), possessives (×my×,×your×), and quantifiers (×some×,×many×).
Determiners are a closed class.

Words Can Belong to Different Classes

The same word can be a different word class depending on how it is used in a sentence.
For example,×run×can be a verb (×I run every day×) or a noun (×I went for a run×).
Similarly,×light×can be a noun (×the light is bright×), an adjective (×a light bag×), or a verb (×to light a candle×).
Always consider the word's function in the sentence to identify its class.

## Word Classes (Parts of Speech) A **part of speech** (also **word class** or **grammatical category**) is a category of words that share similar grammatical properties. Words in the same class behave similarly in sentences — they play similar roles, and often inflect (change form) in similar ways. ### The main English word classes - **Nouns**: common, proper, abstract, collective. - **Pronouns** - **Verbs**: including **modal** and **auxiliary** verbs. - **Adjectives** - **Adverbs** - **Prepositions** - **Conjunctions**: coordinating and subordinating. - **Determiners** Other classes sometimes listed include interjections, numerals and articles. ### Open vs closed classes - **Open classes** (typically nouns, verbs, adjectives) acquire new members constantly. - **Closed classes** (such as pronouns and conjunctions) acquire new members infrequently, if at all. ### One word, different classes A single word can belong to different classes in different sentences. Always judge a word by the job it is doing in that sentence, not by the word alone. ### Why classification matters Languages differ in how many word classes they have and how those classes behave. For example, Japanese has as many as three classes of adjectives where English has one, and many languages do not distinguish between adjectives and adverbs. Because of this variation, parts of speech must be analysed for each individual language. ### Key historical point Classification of words into lexical categories is found from the earliest moments in the history of linguistics. The Greek scholar Plato wrote that sentences are a combination of verbs and nouns; Aristotle added a class of 'conjunction'. By the end of the 2nd century BCE, grammarians had expanded this into eight categories. The Latin grammarian Priscian later modified the system, excluding 'article' (Latin has no articles) and adding 'interjection'. ### Exam tips - Identify the word's **role** in the sentence before naming its class. - Learn the sub-types: common/proper/abstract/collective nouns; modal/auxiliary verbs; coordinating/subordinating conjunctions. - Remember that **open** classes grow; **closed** classes rarely do.

part of speech: A category of words (or, more generally, of lexical items) that have similar grammatical properties. Also known as word class or grammatical category.
word class: Another term for part of speech; a category of words that share similar grammatical properties.
open class: A word class that acquires new members constantly (typically nouns, verbs and adjectives).
closed class: A word class that acquires new members infrequently, if at all (such as pronouns and conjunctions).
noun: A word class that includes common, proper, abstract and collective nouns.
verb: A word class that includes modal and auxiliary verbs.
adjective: A word class that describes or modifies a noun.
adverb: A word class that modifies a verb, adjective, clause, sentence, or another adverb.
pronoun: A word class that can substitute for a noun.
preposition: A word class placed before other words to show relationships.
conjunction: A word class that binds together discourse; includes coordinating and subordinating conjunctions.
determiner: A word class that introduces and specifies a noun.
