Relative clauses are clauses that begin with relative pronouns like who, that, which, whose, where, when to provide additional information about a noun. There are two types - defining relative clauses that identify the noun and non-defining clauses that provide extra information. Relative pronouns can sometimes be omitted in spoken English, especially when they are the object of the clause or when the clause uses a present or past participle with the verb "to be".
