That vs Which

A clause is an important aspect of the English Language. The clause is a set of words that contain a verb and is also a part of a sentence.

A relative clause is one type of clause that expresses the person or a thing that the speaker is referring to. The most common relative clauses that are in use are who, whose, whom, that, and which.

The last two relative clauses are often confused. Though they sound alike while used in a sentence, if misused instead of the correct clause is considered grammatically wrong.
