We usewhichin indirect questions and statements:

We usewhichin relative clauses to refer to animals and to things:

We also usewhichto introduce a relative clause when it refers to a whole clause or sentence:

We often usewhichwith prepositions. Some formal styles prefer to use a preposition beforewhichrather than to leave the preposition ‘hanging’ at the end of the sentence:
