Grammar is the engine and vocabulary is the fuel. Together they let you build sentences that are clear, varied and powerful. Master the mechanics here and every piece of writing you produce — from stories to exam essays — will improve.

This lesson focuses on Word Classes: name the eight parts of speech and use each one correctly.

Definition: Word Classes

Name the eight parts of speech and use each one correctly.

Key ideas

The eight word classes

Every word belongs to a class defined by its job in a sentence. Nouns name people, places or things (teacher, London, courage). Verbs express actions or states (run, is, believe). Adjectives describe nouns (quick, blue, enormous). Adverbs describe verbs, adjectives or other adverbs, often ending in -ly (quickly, very, yesterday). Pronouns stand in for nouns (she, they, it). Prepositions show relationships of place, time or direction (under, before, towards). Conjunctions join words or clauses (and, but, because). Interjections express sudden feeling (wow, ouch, hey).

How word classes work together

Word classes team up to build meaning. Adjectives modify nouns (the enormous dog), while adverbs usually modify verbs (barked loudly) — swapping them changes the sense. Prepositions always come before a noun or pronoun to make a phrase (under the table, with her). Once you can label each word's class, you can spot exactly why a sentence works — or why it fails.

Key term — noun: A word that names a person, place, thing or idea: teacher, London, courage.

Worked example: Word Classes

Label the word class of each word: She laughed loudly and clapped.

She is a pronoun — it stands in for a noun. Laughed is a verb — it expresses the action. Loudly is an adverb — it describes how she laughed (ends in -ly, describing a verb). And is a conjunction — it joins the two verbs. Clapped is a verb — the second action.

Answer: She (pronoun), laughed (verb), loudly (adverb), and (conjunction), clapped (verb).

Common mistakes
  • Calling every describing word an adjective Adjectives describe nouns (a loud parrot), but words describing verbs are adverbs (squawked loudly). If it answers "how?", it is probably an adverb.
  • Confusing prepositions with conjunctions Prepositions come before a noun to show place or time (under the table, before lunch); conjunctions join words or clauses (fish and chips, I ran because I was late).

Practice

Identify the word class: courage in 'It takes courage to apologise.'
Person, place, thing or idea?

Noun — it names an idea.

Identify the word class: although in 'Although it rained, we played on.'
Does it join two clauses?

Conjunction — it joins the subordinate clause to the main clause.

Identify the word class: very in 'a very tall building'.
What does it describe — the noun or the adjective?

Adverb — it describes the adjective tall, not the noun building.

Identify the word class: hey in 'Hey! Watch out!'
Does it express sudden feeling?

Interjection — it expresses a sudden reaction.

  • The eight word classes: Noun, verb, adjective, adverb, pronoun, preposition, conjunction and interjection — each defined by its job in the sentence.
  • How word classes work together: Adjectives modify nouns, adverbs modify verbs or adjectives, and prepositions introduce phrases.
