We have seen in the previous sections that a clause is a group of words, with a subject and/or a predicate, having a meaning.
At the same time, Adverb is a word which gives an additional detail about the meaning of a verb or an adjective or another adverb.
When a clause plays the role of an adverb that adverb is called ADVERB-CLAUSE.
• They rested when evening came.
Here the clause ‘when evening’ came is modifying the verb ‘rested’. So that clause is a adverb-clause.
An adverb-clause is a group of words which contains a subject and a predicate of its own and does the work of an adverb.
• You may sit where you like.
In this sentence, the clause ‘where you like’ is an adverb-clause.
• He fled where his pursuers could not follow.
‘Where his pursuers could not follow’ is the adverb-clause.
• He behaves as one would expect him to do.
‘As one would expect him to do’ is the adverb-clause.
• I shall punish you because you have committed this.
‘You have committed this’ is an adverb-clause.
• Will you wait till I return?
“Till I return’ is the adverb-clause.
In these sentences the adverb-clauses have been colored blue.
• Do not go when you father comes to this town.
• He is not clever that he lost all his property.

In many sentences, the adverb-phrase can be replaced with an adverb-clause as follows.
• Do it to the best of your ability.
In this sentence, the adverb-phrase can be replaced with an adverb-clause.
• Do it as well as you can.
Both these sentences convey the same meaning.
• The Dean was met on his arrival by his secretary.
The adverb-phrase ‘on his arrival’ can be replaced with adverb-clause ‘when he arrived’ to convey the same meaning.
• When he arrived the Dean was met by his secretary.
Few more examples with the adverb-phrases replaced with their corresponding adverb-clauses.
