Identify the kind of Adverb used in the following sentence: I have he…

The correct answer is Option (2) → Adverb of time

An adverb is a word that tells how, when, where or how much something happens. It can also describe an adjective or another adverb, for example she sings sweetly, very hot.

In "I have heard him before", the word answers the question "When have I heard him?": at an earlier time.

Option	What it tells	Example
(1) Adverb of reason	An adverb of reason tells why (therefore, hence). "Before" gives no reason.	He was ill and therefore stayed at home.
(2) Adverb of time (answer)	An adverb of time tells when an action takes place: now, then, today, soon, already, before, ago.	I have seen this film before.
(3) Relative adverb	A relative adverb (where, when, why) joins a clause to a noun. "Before" joins nothing here.	This is the house where I was born.
(4) Adverb of manner	An adverb of manner tells how (slowly, carefully). "Before" tells when.	She sings beautifully.
