Subjects, Objects and Predicates Explained


The subject of a sentence is the entity that performs the action described by the verb or is being described in the sentence. It is usually a noun, pronoun, or noun phrase that indicates who or what the sentence is about. In simpler terms, the subject tells you who or what is doing something in the sentence.

For example:

"John ate the cake." (The subject is "John.")

"The cat is sleeping." (The subject is "The cat.")

"They are running." (The subject is "They.")


The object is the noun, pronoun, or noun phrase that receives the action of the verb or is affected by the action. Not all sentences have objects, but in those that do, the object typically follows the verb and completes the predicate. Objects can be direct objects, which directly receive the action of the verb, or indirect objects, which are affected by the action indirectly.

Direct Object: It receives the action of the verb directly.

For example: "John ate the cake." (The direct object is "the cake.")

Indirect Object: It indirectly receives the action of the verb, often preceded by a preposition like "to" or "for."

For example: "John gave the cake to Mary." (The indirect object is "Mary.")


The predicate is the part of the sentence that contains the verb and provides information about the subject. It usually consists of the verb along with any other words that modify or complete the action or state expressed by the verb. In essence, the predicate tells us something about the subject or what the subject is doing.

For example:

"John ate the cake." (The predicate is "ate the cake.")

"The cat is sleeping." (The predicate is "is sleeping.")

"They are running." (The predicate is "are running.")
