what part of speech is the word how
The word “how” is usually an adverb, but it can play several roles depending on how it’s used in a sentence.
Main answer: the usual case
Most of the time, “how” is an interrogative adverb.
- It asks “in what way?” or “to what extent?”
- “How did you do that?” → asks about the manner.
* “How often do you go to the gym?” → asks about frequency/degree.
* “How high can you jump?” → asks about degree.
In these questions, “how” modifies a verb, adjective, or another adverb, so it’s functioning as an adverb.
Other roles “how” can have
In modern grammar descriptions, “how” is described as multi‑functional.
- Adverb in exclamations
- “How beautiful!” / “How kind you are!”
It still modifies an adjective (“beautiful,” “kind”), so it is adverbial here.
- Subordinating conjunction / marker of an embedded question
- “I don’t know how he did it.”
* “Tell me how you solved it.”
Here “how” introduces a clause (“how he did it”), functioning like a conjunction or complementizer that links the clause to the main verb (“know,” “tell”).
- Noun (the ‘how’ = the method)
- “I can show you the how and why of this process.”
In this kind of usage, “how” names the method or manner itself, so it’s treated as a noun.
- Interjection in certain idioms (mainly American English)
- “And how!” meaning “Absolutely!” or “You’re so right!”
In this fixed exclamation, dictionaries class it as an interjection‑like use.
Simple takeaway
- In sentences like “How are you?” or “How does this work?” it’s an interrogative adverb.
- It can also act as a subordinator (“I know how it works”), a noun (“the how of it”), and in set phrases as something close to an interjection (“And how!”).
