Relative clauses are a very useful way of adding extra information to a sentence in English. It can tell us more about the sentence. It is also a very helpful way to help us connect two sentences together, which will improve our writing in English.

We add extra information to a sentence by using a relative pronoun like 'which' or 'who'. We can also use relative adverbs like 'where' or 'when'.

In English, we have both defining and non-defining relative clauses. This means that a defining relative clause gives us information we need to understand the sentence, whereas a non-defining relative clause just gives us useful information. This may be helpful but not necessary to understanding the whole sentence.
