Question

Which clause is ' if it rains ' ?

Answer 1

conditional clause is the answer

Answer 2

'If it rains' is the dependent clause.

A dependent clause is the clause which cannot stand alone in its meaning on the other hand independent clause refers to the phrase which can stand alone, though both have a subject and a verb.

Since, in the above question, sentence begins from 'if' therefore, it is the dependent clause, as it doesn't convey complete meaning.
