Identify the kind of Adverb used in the following sentence:

I have heard him before.

Adverb of time

The correct answer is OPTION 2 Adverb of time

The kind of Adverb used in the sentence "I have heard him before." is: Adverb of time

In the sentence "I have heard him before," the adverb "before" is indicating when the action of hearing took place. Adverbs of time answer the question "When?" or "How often?" in a sentence. In this case, "before" specifies the time at which the speaker heard him. Therefore, "before" functions as an adverb of time in this context.

1. Adverb of reason:

   • Adverbs of reason provide information about why an action occurred. For example, "because," "therefore," "consequently," etc. In the given sentence, there is no adverb indicating the reason for hearing him, so it's not an adverb of reason.

2. Relative adverb:

   • Relative adverbs introduce relative clauses and include words like "where," "when," and "why." In the given sentence, "before" is used as an adverb of time, not as a relative adverb introducing a relative clause.

3. Adverb of manner:

   • Adverbs of manner provide information about how an action is performed. Examples include "quickly," "slowly," etc. In the given sentence, there is no adverb indicating the manner in which the speaker heard him, so it's not an adverb of manner.
