What Are the Parts of Speech? Identify a Word’s Job in a Sentence

The traditional eight parts of speech are nouns, pronouns, verbs, adjectives, adverbs, prepositions, conjunctions and interjections. These categories describe how words work in sentences. To identify one, look at what the word does in that particular sentence rather than memorizing a single label for it.

For example, paint is a noun in “The paint dried” and a verb in “We paint furniture.” The spelling stays the same while the grammatical use changes. This guide uses the traditional eight-category framework, then explains why other references may include determiners separately.

The eight parts of speech, with examples

The Language Portal of Canada’s HyperGrammar introduction presents these eight traditional categories and emphasizes use in context. The examples below are original. Bold type marks the word being classified, not every word belonging to that class.

Part of speech	Typical use	Example
Noun	Names an entity, place, substance, event or idea.	The proposal needs work.
Pronoun	Can stand in a position otherwise filled by a noun phrase.	They approved the proposal.
Verb	Expresses an action, occurrence or state; also includes helping verbs.	The office seems quiet.
Adjective	Describes or characterizes a noun or pronoun.	We chose a quiet office.
Adverb	Modifies a verb, adjective, another adverb or a larger statement.	The courier arrived early.
Preposition	Introduces a phrase expressing a relationship such as place or time.	The parcel is beside the door.
Conjunction	Connects words, phrases or clauses.	We called because the parcel was late.
Interjection	Expresses a reaction or response, often apart from the main clause.	Oh, the parcel is here.

These descriptions are starting points. A noun can name an abstract idea such as patience, and a preposition can express a relationship other than physical position, as in “during lunch.” Meaning helps, but the surrounding grammatical structure provides stronger evidence than a definition alone.

Why do some lists include determiners?

Words such as the, a, this and some help specify which thing or how much is meant. Many grammatical descriptions group these as determiners. In “that narrow doorway,” that identifies the doorway while narrow describes it.

Traditional accounts often place some of these words under adjectives, with labels such as demonstrative adjective. Other frameworks separate determiners and divide additional categories differently. The University of Glasgow’s word-class reference, for instance, lists determiners separately. A different category count does not automatically make a reference wrong. Check its definitions and use its terminology consistently.

Work through one complete sentence

“Oh, they carefully packed fragile cups into boxes and left.” This short sentence contains examples of all eight traditional classes without requiring every sentence to do so.

Oh is an interjection expressing a reaction. They is a pronoun. Carefully is an adverb modifying packed. Both packed and left are verbs. Fragile is an adjective describing the noun cups. Into is a preposition introducing into boxes, and boxes is another noun. And is a conjunction linking the two coordinated verb phrases.

Notice the difference between a word and a phrase. Into is one preposition; into boxes is a prepositional phrase. Calling the whole phrase a preposition would hide the noun inside it. When analyzing a longer passage, mark phrase boundaries before assigning labels to unfamiliar words.

Word class is different from sentence role

A part of speech tells you a word’s grammatical category. A sentence role tells you how a word or phrase functions in a particular construction. In “Maya called Leo,” both names are nouns. Maya is the subject, while Leo is the direct object. In “Leo called Maya,” their roles switch, but both remain nouns.

The same distinction applies to pronouns. In “They called us,” they and us are pronouns with different sentence roles. Answering “subject” when asked for a part of speech mixes two levels of analysis. First identify the category, then describe the role if needed.

Use context instead of unreliable shortcuts

An ending can offer a clue without settling the question. Quickly is an adverb, but so are often and very. Meanwhile, friendly is an adjective in “a friendly neighbor.” Canada’s adverb reference explains why grammatical relationships matter more than spotting an -ly ending.

Verbs also extend beyond visible actions. In “I know the route,” know is a verb. In “The room is warm,” is is a verb connecting the subject to a description. Helping verbs count too: in “They have finished,” have supports finished in the verb phrase. The HyperGrammar verb guide includes actions, events and states.

For a practical check, ask which words the target connects to. Does it describe a noun, modify a verb, or introduce a relationship? If the sentence is ambiguous, keep both possible readings until the context resolves them.

Check dictionary labels, then try it yourself

Dictionaries commonly use labels such as n., v., adj. and adv., or spell the category out. Read the dictionary’s key and match the relevant meaning and example to your sentence. One entry may contain several classes. The British Council’s parts-of-speech overview highlights how these labels help with dictionary use.

Identify the bold words before reading the answers: “Please record the result.” “Keep a record.” “The train arrived late.” “A late train delayed us.” “We waited because it rained.”

Answers: Record is a verb in the first sentence and a noun in the second. Late is an adverb modifying arrived, then an adjective describing train. Because is a conjunction introducing the reason clause. Each answer depends on the word’s use, not just its spelling.

Word classes can also help when checking headings, although capitalization follows a chosen style. For that separate editing step, see our guide to changing text case without retyping.

If you prefer a print reference beside your notebook, browse English grammar reference books on Amazon. Look for clear definitions, a terminology key and examples that explain the choices.
