An object pronoun is a type of personal pronoun that is normally used as a grammatical object, either as the direct or indirect object of a verb, or as the object of a preposition. These pronouns always take the objective case, whether they are indirect object pronouns or direct object pronouns.
The seven basic pronouns take on different forms when used as object pronouns rather than as subject pronouns:
If you know how to find the object of a sentence, then you will find it very easy to identify an object pronoun when you see one. To find the object of a sentence, locate the nouns and verbs and mentally separate them from the rest of the words the sentence contains. Both the subject and object of the sentence will be nouns or pronouns. The subject will be the one doing the action the verb describes. The object is the noun or pronoun receiving the action. Making things even simpler, when the object is not a noun, it's an object pronoun.
Just like subject pronouns, object pronouns can be singular or plural, masculine, feminine, or gender neutral. The masculine or feminine subject pronoun is used whenever the gender is known. When referring to the weather, temperature, time, an inanimate object or a child or animal of undetermined gender, the neuter form "it" can be used.
In the following examples, the subject is in bold, the verb is in italics, and the object pronoun is in bold and is underlined.
