I/me, he/him, they/them etc.

This lesson explains the difference between subject pronouns and object pronouns. Subject pronouns perform the action in a sentence. Object pronouns receive the action or follow a preposition.

• Subject pronouns: I, you, he, she, it, we, they — used as the subject of a verb.
• Object pronouns: me, you, him, her, it, us, them — used after verbs and prepositions.
• Use the correct form to make sentences clear and grammatical in both formal and informal contexts.

Identify the role of the pronoun in the sentence:

• As subject (the doer): use subject pronouns — I, you, he, she, it, we, they.
• As object (the receiver) or after a preposition: use object pronouns — me, you, him, her, it, us, them.
• In formal writing, prefer subject pronouns after the verb 'be' (e.g., 'It is I').

Think: Subject = doer; Object = receiver or after prepositions.

Watch for these frequent errors when using subject and object pronouns:

• Using an object pronoun as a subject: 'Me and Sarah called' → incorrect.
• Putting subject pronouns after prepositions: 'between you and I' → incorrect.
• Mixing pronoun forms in compound subjects: choose the subject form for the whole subject.
• Relying on spoken informal forms in formal writing without checking correctness (e.g., 'It is me' vs 'It is I').

Always check the pronoun's role: subject = use subject pronoun; object or after preposition = use object pronoun.
