In grammar, “what type of word is that?” is basically asking: “What part of speech is this word in this sentence?”

The core idea

Every word in a sentence belongs to a part of speech based on what it’s doing there.

Common “types of words” (parts of speech) include:

  • Noun – names a person, place, thing, or idea (“cat”, “London”).
  • Verb – shows an action or state (“run”, “is”).
  • Adjective – describes a noun (“blue”, “happy”).
  • Adverb – describes a verb, adjective, or another adverb (“quickly”, “very”).
  • Pronoun – replaces a noun (“she”, “they”).
  • Determiner – points to or specifies a noun (“this book”, “that dog”).
  • Conjunction – joins words or clauses (“and”, “but”, “because”, “that” in “I think that you’re right”).
  • Preposition – shows relationship in time/space (“on”, “under”, “before”).
  • Interjection – short exclamation (“oh!”, “wow!”).

So when someone says “what type of word is that?”, they want to know whether the word is acting as a noun, verb, adjective, etc., in that particular context.

If you share a specific sentence (for example: “I know that you’re tired”), I can point out exactly what type of word each one is.
