Object pronouns replace a noun phrase that receives the action of a verb or appears after a preposition. They help you avoid repeating names and make sentences smoother. In English, object pronouns change form depending on whether they are the object. Use them as direct objects, indirect objects, and objects of prepositions.

English object pronouns have specific forms that differ from subject pronouns. The full set is: me, you, him, her, it, us, them. These forms stay the same whether the object is direct, indirect, or after a preposition.

Word/Phrase	Definition	Example
me	object form for I	She saw me.
you	object form for you	I called you.
him	object form for he	We invited him.
her	object form for she	I helped her.
it	object form for it	Put it there.
us	object form for we	They asked us.
them	object form for they	I met them.

Use an object pronoun as the direct object when it receives the verb’s action directly. It usually answers what or whom after the verb. The pronoun typically comes right after the main verb or after the verb and particle depending on the structure.

Use an object pronoun as the indirect object when it receives the direct object. It typically answers to whom or for whom. Indirect object pronouns often appear right after the verb and before the thing being given, told, sent, or shown.

After a preposition, use an object pronoun, not a subject pronoun. This includes prepositions of place, time, and relationship such as to, for, with, at, about, from, and between. The object pronoun is the complement of the preposition.

Object pronouns usually come after the verb in English. With two objects, the common patterns are verb + indirect object pronoun + direct object, or verb + direct object + to or for + object pronoun. Choose the pattern that sounds natural and keeps the meaning clear.

Rule	Example
Put the object pronoun after the verb	I saw him yesterday.
With two objects, place the indirect object pronoun before the direct object	She gave me the keys.
Or use to or for before the object pronoun	She gave the keys to me.

With phrasal verbs, object pronoun placement is more restricted than with full nouns. If the phrasal verb is separable, the object pronoun must go between the verb and the particle. If the phrasal verb is inseparable, the object pronoun comes after the whole verb phrase.

Rule	Example
Separable phrasal verb: pronoun goes between verb and particle	Turn it off.
Inseparable phrasal verb: pronoun goes after the verb phrase	Look after them.

Choose me, him, her, us, and them when the pronoun is an object, even if it is part of a pair. In careful writing, object form is standard after verbs and prepositions. In very informal speech, some people use I in coordination, but it is not considered standard.

Rule	Example
After a verb, use object form	She invited Alex and me.
After a preposition, use object form	This is for you and him.

In formal English, whom is used as an object, and who is used as a subject. In everyday conversation, many speakers use who in most positions, but whom still appears after prepositions and in very formal writing. If the pronoun could be replaced by him or them, whom is the traditional choice.

Rule	Example
Use whom as an object in formal style	Whom did you see?
After a preposition, whom is common in formal style	To whom should I speak?
In casual speech, who often replaces whom	Who did you see?

Object pronouns can create ambiguity if it is unclear what the pronoun refers to. Make sure the pronoun has a clear, recent antecedent and matches it in meaning. For emphasis, English can stress the pronoun in speech or use a full noun instead of a pronoun when needed.
