Relative clauses are added clauses that give more information about a subject.
Why use relative clauses?
Relative clauses can add more information about a subject.
They are used as a way to break up subject-verb-object (although they can also be added to many other forms – passive, time phrases, prepositions etc.)
The easiest way to insert a relative clause is to use punctuation to pause a sentence, add the clause, use more punctuation, then continue the sentence.
