By Shailendra Singh

Updated on 28 Oct 2025, 11:17 IST

The subject in a sentence is the person, animal, or thing that performs the action or is being talked about. It typically appears before the verb and answers the question "Who/What is doing the action?" 

Example: In "John runs," "John" is the subject.

What is an Object?

The object is the person, animal, or thing that receives the action of the verb or is affected by it. It usually follows the verb and answers "Whom/What is receiving the action?" There are two kinds: direct and indirect object.

What is a Direct Object?

A direct object is the noun or pronoun that receives the action of a verb directly. It answers the question “what?” or “whom?” after the verb.

Example:

  • She wrote a letter.
    “a letter” is the direct object because it receives the action of “wrote.”

What Is an Indirect Object?

An indirect object tells to whom or for whom the action is done. It appears before the direct object and often refers to a person.

Example:

  • She wrote her friend a letter.
    “her friend” is the indirect object, and “a letter” is the direct object.

Quick Way to Identify Them

  1. Find the verb.
  2. Ask “what?” or “whom?” → direct object.
  3. Ask “to whom?” or “for whom?” → indirect object.

Example

  • He gave his mother a gift.
    • Verb: gave
    • Direct Object: a gift (what he gave)
    • Indirect Object: his mother (to whom he gave it)
