Every sentence you have ever spoken or written is built from just a handful of word types. Learn to recognise all eight, and grammar stops being a mystery.
Before a sentence can carry meaning, its words must each play a role — naming, doing, describing, linking. That role is called a part of speech.
English has eight parts of speech. Every single word you use, no matter how long or short, belongs to one of these eight categories depending on the job it is doing in a sentence. Some words can even change category depending on how they are used — which is exactly why understanding the categories, rather than memorising individual words, is what actually makes grammar make sense.
This guide walks through each part of speech in turn, with clear definitions and examples, before testing your understanding with ten practice questions at the end.
A noun names a person, place, thing, or idea. Nouns are the labels we attach to everything that exists — physical objects, living beings, locations, and even abstract concepts that cannot be touched.
Person: teacher, Sarah, doctor
Place: school, London, kitchen
Thing: book, laptop, mountain
Idea: honesty, freedom, happiness
Nouns are further divided into common nouns (general: city, dog) and proper nouns (specific, always capitalised: Paris, Rex). There are also countable nouns (books, chairs) and uncountable nouns (water, information) — a distinction that trips up even confident writers.
A pronoun replaces a noun so that language does not become repetitive. Without pronouns, we would have to repeat the same name or object again and again in every sentence.
"Maria picked up Maria's bag and Maria left" becomes "Maria picked up her bag and she left."
Common pronouns include: he, she, it, they, we, this, those, who, myself, and someone. Pronouns must agree in number and gender with the noun they replace.
A verb expresses an action, occurrence, or state of being. Every complete sentence needs at least one verb — it is the engine that makes the sentence move.
Action: run, write, calculate
Occurrence: become, happen, occur
State of being: is, seem, appear
Verbs change form to show tense (walk, walked, will walk), and can be regular (following a predictable pattern) or irregular (go, went, gone).
An adjective describes or modifies a noun or pronoun, adding detail about size, colour, quantity, quality, or other characteristics.
The tall, ancient, weathered castle stood on the hill. (Each bolded word modifies "castle.")
Adjectives typically appear directly before the noun they describe, or after a linking verb such as "is" or "seems" (e.g., "The castle is ancient.").
An adverb modifies a verb, an adjective, or even another adverb — usually describing how, when, where, or to what extent something happens. Many (though not all) end in -ly.
She spoke quietly (modifies the verb "spoke"). The exam was extremely difficult (modifies the adjective "difficult").
A preposition shows the relationship between a noun (or pronoun) and another word in the sentence — usually relating to place, time, or direction.
The keys are on the table. We will meet after lunch. She walked through the door.
A conjunction joins words, phrases, or clauses together. Without conjunctions, every sentence would have to stand entirely alone.
Coordinating: and, but, or, so — join equal ideas.
Subordinating: because, although, if — join a main idea to a dependent one.
An interjection expresses sudden emotion — surprise, joy, pain, or hesitation — and usually stands apart from the rest of the sentence, often followed by an exclamation mark.
Wow! That's incredible. Ouch! That hurt. Well, I suppose that's true.
| Part of Speech | Job | Example |
|---|---|---|
| Noun | Names a person, place, thing, idea | teacher, London, freedom |
| Pronoun | Replaces a noun | he, this, someone |
| Verb | Shows action or state | run, is, become |
| Adjective | Describes a noun | tall, blue, three |
| Adverb | Modifies a verb/adjective | quickly, very, here |
| Preposition | Shows relationship | on, after, through |
| Conjunction | Joins words or clauses | and, because, but |
| Interjection | Expresses sudden emotion | wow, ouch, well |
Read this text message: "Wow, that new phone is incredibly expensive, but Sarah still bought it for herself because she loves gadgets." In just one sentence: Wow is an interjection, that and Sarah relate to nouns, is/bought/loves are verbs, new/expensive/incredible are adjectives and adverbs, herself/she are pronouns, and but/because are conjunctions. Every single word, in every sentence you will ever write, falls into one of these eight categories.
Understanding parts of speech is not an academic exercise — it is the foundation for everything else in grammar. You cannot fix a sentence structure problem, correct a punctuation error, or improve your writing style without first being able to identify what job each word is doing. This is exactly why Parts of Speech is topic one in our Grammar Basics series: everything that follows builds on it.
