Noun vs. Verb: What's the Difference?
They're the two most fundamental building blocks of a sentence. A noun names something — a person, place, thing, or idea. A verb tells you what that thing does or is — its action or state of being. In 'The dog runs', 'dog' is the noun (what we're talking about) and 'runs' is the verb (what it does). Most sentences need both.

Which should you use?
Noun
It's a noun when the word names a thing — what the sentence is about, like 'the teacher' or 'a song'.
Verb
It's a verb when the word shows what's happening — the action or state, like 'sings' or 'is'.
Frequently asked questions
- What's the main difference between a noun and a verb?
- A noun names something (a person, place, thing, or idea); a verb expresses an action or state of being. The noun is what the sentence is about; the verb is what it does or is.
- Can the same word be both a noun and a verb?
- Yes — many words can be either, depending on use. 'Run' is a verb in 'I run daily' but a noun in 'I went for a run'. The job it does in the sentence decides which it is.
- Does every sentence have a noun and a verb?
- Almost always. A complete sentence needs a verb, and usually a noun (or pronoun) as its subject — the thing doing or being something.
