Compound Subject

Compound Subjects

Definition:

• A compound subject consists of two or more nouns or pronouns joined by a coordinating conjunction, sharing the same verb and collectively performing the action or being described.
• Example: In “Tom and Sarah played basketball,” the compound subject is “Tom and Sarah.”

Coordinating Conjunctions:

• Compound subjects are connected by coordinating conjunctions such as “and,” “or,” or “nor.”
• Example: “The teacher or the students will present the project.”

Subject-Verb Agreement with Compound Subjects

1. Singular Subjects:

• When both parts of the compound subject are singular and connected by “and,” the verb is plural.
• Example: “Anna and Peter are going to the concert.”

2. Mixed Subjects:

• When connected by “or” or “nor,” the verb agrees with the subject closest to it.
• Example: “Neither the cat nor the dogs are in the yard.”
