Question

This is the place......... (add a defining relative clause)

Answer 1

This is the place where I was born.As the name indicates, relative clauses may be defined or provide essential information to define or identify the person or a thing.

For example the sentence: Dogs that like cats are very unusual in nature. In this sentence, we understand that their dogs in the world, but we limiting only ones that like cats.

The defining relative clause provides that information. If the defining relative clause were eliminated from the sentence, the sentence would still be correct grammatically, but its meaning will be changed significantly.
