1 answer

relative pronoun which is used with a non-essential clause.

An essential clause provides information that is necessary to the meaning of the sentence and cannot be removed without changing the overall meaning. In this case, the relative pronoun "that" is used.

Example:
The book that I bought yesterday is really interesting.

In this sentence, "that I bought yesterday" is an essential clause because it is necessary to identify which book is being referred to.

A non-essential clause, on the other hand, provides additional information that is not necessary to the meaning of the sentence. In this case, the relative pronoun "which" is used.

Example:
The book, which I bought yesterday, is really interesting.

In this sentence, "which I bought yesterday" is a non-essential clause because it adds extra information about the book but can be removed without changing the overall meaning of the sentence.
