π What are Relative Clauses?
Relative clauses are a type of subordinate clause that modify a noun or noun phrase. They provide additional information about the noun they are modifying, adding detail and clarity to your writing. They typically begin with relative pronouns (who, whom, which, that) or relative adverbs (where, when, why).
