Words don’t only mean something; they also do something. In the English language, words are grouped into word classes based on their function, i.e. what they do in a phrase or sentence. In total, there are nine word classes in English.
Word class meaning and example
All words can be categorised into classes within a language based on their function and purpose.
An example of various word classes is ‘The cat ate a cupcake quickly.’
-
The = a determiner
-
cat = a noun
-
ate = a verb
-
a = determiner
-
cupcake = noun
-
quickly = an adverb
Word class function
The function of a word class, also known as a part of speech, is to classify words according to their grammatical properties and the roles they play in sentences. By assigning words to different word classes, we can understand how they should be used in context and how they relate to other words in a sentence.
Each word class has its own unique set of characteristics and rules for usage, and understanding the function of word classes is essential for effective communication in English. Knowing our word classes allows us to create clear and grammatically correct sentences that convey our intended meaning.
Word classes in English
In English, there are four main word classes; nouns, verbs, adjectives, and adverbs. These are considered lexical words, and they provide the main meaning of a phrase or sentence.
The other five word classes are; prepositions, pronouns, determiners, conjunctions, and interjections. These are considered functional words, and they provide structural and relational information in a sentence or phrase.
Don’t worry if it sounds a bit confusing right now. Read ahead and you’ll be a master of the different types of word classes in no time!
All word classes | Definition | Examples of word classification |
Noun | A word that represents a person, place, thing, or idea. | cat, house, plant |
Pronoun | A word that is used in place of a noun to avoid repetition. | he, she, they, it |
Verb | A word that expresses action, occurrence, or state of being. | run, sing, grow |
Adjective | A word that describes or modifies a noun or pronoun. | blue, tall, happy |
Adverb | A word that describes or modifies a verb, adjective, or other adverb. | quickly, very |
Preposition | A word that shows the relationship between a noun or pronoun and other words in a sentence. | in, on, at |
Conjunction | A word that connects words, phrases, or clauses. | and, or, but |
Interjection | A word that expresses strong emotions or feelings. | wow, oh, ouch |
Determiners | A word that clarifies information about the quantity, location, or ownership of the noun | Articles like ‘the’ and ‘an’, and quantifiers like ‘some’ and ‘all’. |
The four main word classes
In the English language, there are four main word classes: nouns, verbs, adjectives, and adverbs. Let’s look at all the word classes in detail.
Nouns
Nouns are the words we use to describe people, places, objects, feelings, concepts, etc. Usually, nouns are tangible (touchable) things, such as a table, a person, or a building.
However, we also have abstract nouns, which are things we can feel and describe but can’t necessarily see or touch, such as love, honour, or excitement. Proper nouns are the names we give to specific and official people, places, or things, such as England, Claire, or Hoover.
Cat
House
School
Britain
Harry
Book
Hatred
‘My sister went to school.‘
Verbs
Verbs are words that show action, event, feeling, or state of being. This can be a physical action or event, or it can be a feeling that is experienced.
Lexical verbs are considered one of the four main word classes, and auxiliary verbs are not. Lexical verbs are the main verb in a sentence that shows action, event, feeling, or state of being, such as walk, ran, felt, and want, whereas an auxiliary verb helps the main verb and expresses grammatical meaning, such as has, is, and do.
Run
Walk
Swim
Curse
Wish
Help
Leave
‘She wished for a sunny day.’
Adjectives
Adjectives are words used to modify nouns, usually by describing them. Adjectives describe an attribute, quality, or state of being of the noun.
Long
Short
Friendly
Broken
Loud
Embarrassed
Dull
Boring
‘The friendly woman wore a beautiful dress.’
Fig 1. Adjectives can describe the woman and the dress
Adverbs
Adverbs are words that work alongside verbs, adjectives, and other adverbs. They provide further descriptions of how, where, when, and how often something is done.
Quickly
Softly
Very
More
Too
Loudly
‘The music was too loud.’
All of the above examples are lexical word classes and carry most of the meaning in a sentence. They make up the majority of the words in the English language.
The other five word classes
The other five remaining word classes are; prepositions, pronouns, determiners, conjunctions, and interjections. These words are considered functional words and are used to explain grammatical and structural relationships between words.
For example, prepositions can be used to explain where one object is in relation to another.
Prepositions
Prepositions are used to show the relationship between words in terms of place, time, direction, and agency.
In
At
On
Towards
To
Through
Into
By
With
‘They went through the tunnel.’
Pronouns
Pronouns take the place of a noun or a noun phrase in a sentence. They often refer to a noun that has already been mentioned and are commonly used to avoid repetition.
Chloe (noun) → she (pronoun)
Chloe’s dog → her dog (possessive pronoun)
There are several different types of pronouns; let’s look at some examples of each.
- He, she, it, they — personal pronouns
- His, hers, its, theirs, mine, ours — possessive pronouns
- Himself, herself, myself, ourselves, themselves — reflexive pronouns
- This, that, those, these — demonstrative pronouns
- Anyone, somebody, everyone, anything, something — Indefinite pronouns
- Which, what, that, who, who — Relative pronouns
‘She sat on the chair which was broken.’
Determiners
Determiners work alongside nouns to clarify information about the quantity, location, or ownership of the noun. It ‘determines’ exactly what is being referred to. Much like pronouns, there are also several different types of determiners.
- The, a, an — articles
- This, that, those — you might recognise these for demonstrative pronouns are also determiners
- One, two, three etc. — cardinal numbers
- First, second, third etc. — ordinal numbers
- Some, most, all — quantifiers
- Other, another — difference words
‘The first restaurant is better than the other.’
Conjunctions
Conjunctions are words that connect other words, phrases, and clauses together within a sentence. There are three main types of conjunctions;
-
Coordinating conjunctions — these link independent clauses together.
-
Subordinating conjunctions — these link dependent clauses to independent clauses.
- Correlative conjunctions — words that work in pairs to join two parts of a sentence of equal importance.
For, and, nor, but, or, yet, so — coordinating conjunctions
After, as, because, when, while, before, if, even though — subordinating conjunctions
Either/or, neither/nor, both/and — correlative conjunctions
‘If it rains, I’m not going out.’
Interjections
Interjections are exclamatory words used to express an emotion or a reaction. They often stand alone from the rest of the sentence and are accompanied by an exclamation mark.
Oh
Oops!
Phew!
Ahh!
‘Oh, what a surprise!’
Word class: lexical classes and function classes
A helpful way to understand lexical word classes is to see them as the building blocks of sentences. If the lexical word classes are the blocks themselves, then the function word classes are the cement holding the words together and giving structure to the sentence.
Fig 2. Lexical and functional word classes
In this diagram, the lexical classes are in blue and the function classes are in yellow. We can see that the words in blue provide the key information, and the words in yellow bring this information together in a structured way.
Word class examples
Sometimes it can be tricky to know exactly which word class a word belongs to. Some words can function as more than one word class depending on how they are used in a sentence. For this reason, we must look at words in context, i.e. how a word works within the sentence. Take a look at the following examples of word classes to see the importance of word class categorisation.
The dog will bark if you open the door.
The tree bark was dark and rugged.
Here we can see that the same word (bark) has a different meaning and different word class in each sentence. In the first example, ‘bark’ is used as a verb, and in the second as a noun (an object in this case).
I left my sunglasses on the beach.
The horse stood on Sarah’s left foot.
In the first sentence, the word ‘left’ is used as a verb (an action), and in the second, it is used to modify the noun (foot). In this case, it is an adjective.
I run every day
I went for a run
In this example, ‘run’ can be a verb or a noun.
Word Class — Key takeaways
-
We group words into word classes based on the function they perform in a sentence.
-
The four main word classes are nouns, adjectives, verbs, and adverbs. These are lexical classes that give meaning to a sentence.
-
The other five word classes are prepositions, pronouns, determiners, conjunctions, and interjections. These are function classes that are used to explain grammatical and structural relationships between words.
-
It is important to look at the context of a sentence in order to work out which word class a word belongs to.
Frequently Asked Questions about Word Class
A word class is a group of words that have similar properties and play a similar role in a sentence.
Some examples of how some words can function as more than one word class include the way ‘run’ can be a verb (‘I run every day’) or a noun (‘I went for a run’). Similarly, ‘well’ can be an adverb (‘He plays the guitar well’) or an adjective (‘She’s feeling well today’).
The nine word classes are; Nouns, adjectives, verbs, adverbs, prepositions, pronouns, determiners, conjunctions, interjections.
Categorising words into word classes helps us to understand the function the word is playing within a sentence.
Parts of speech is another term for word classes.
The different groups of word classes include lexical classes that act as the building blocks of a sentence e.g. nouns. The other word classes are function classes that act as the ‘glue’ and give grammatical information in a sentence e.g. prepositions.
The word classes for all, that, and the is:
‘All’ = determiner (quantifier)
‘That’ = pronoun and/or determiner (demonstrative pronoun)
‘The’ = determiner (article)

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.
- Types of Word Classes
- Open and Closed Word Classes
- Open Word Classes
- Closed Word Classes
- How to identify the word classes in a sentence?
- 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.

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.
Word classes are parts of speech. They’re the building blocks that form every sentence ever uttered. They are categorized by the role they play in your sentences.
Everyone agrees on the following four main word classes:
- Noun
- Verb
- Adjective
- Adverb
There are varying opinions as to whether the following are word classes or word forms. So we went straight to the experts: the Oxford and Cambridge Dictionaries. Per these two highly learned sources, the following are considered word classes also:
- Pronoun (e.g. I, you, me, we, mine, someone, he, she)
- Preposition (e.g. at, in, on, across, behind, for)
- Conjunction (e.g. and, but, when, if, because)
- Determiner (e.g. a, the, an, this, etc.)
- Exclamation or Interjection (e.g. oh, ah, wow, ouch)
The four main classes have thousands of members, and new nouns, verbs, and other words are being created every day. Consider the verb “google.” This verb didn’t exist just a few years ago and now it is firmly entrenched in everyday language. Just last month a new noun, “intersectionality” (the study of overlapping social identities and related systems of discrimination), was just added to Dictionary.com. Can you think of any other words that have recently been created and entered your own vocabulary?
Some words, however, can fall in multiple word classes depending on their context:
- Put your money in the bank. (noun)
- He began to bank the airplane into the wind. (verb)
- Come warm up by the fire. (noun)
- He will certainly fire her for coming in late again. (verb)
- A book is a source of endless reading pleasure. (noun)
- Book your holiday plans soon to get the best deal. (verb)
- She loves fast cars. (adjective)
- He’s driving fast to get to work on time. (adverb)
- Her hourly complaints have got to stop. (adjective)
- The weather report is reported hourly. (adverb)
The next step is to use your word classes to form phrase classes, like noun phrases, verb phrases, adjective phrases, etc. But we’ll save that for another post.
