When to Omit the Pronoun
In defining relative clauses, you can (and often should) omit the relative pronoun when it is the object of the clause. A simple test is to look at the word after the pronoun:
- If it’s a new subject (I, you, the boy, she…), the pronoun is the OBJECT. → You can omit it.
- If it’s a verb, the pronoun is the SUBJECT. → You cannot omit it.
Object: The cake (that) you baked… (Pronoun is followed by subject ‘you’)
Subject: The dog that barks… (Pronoun is followed by verb ‘barks’)
