Is this a compound sentence? 'John and Hary sang well.'

This sentence can be resolved into two independent clauses: John sang well, and Hary sang well.

Wren and Martin grammar says that if a sentence with compound subject can be resolved into two independent clauses, it's a compound sentence. But I'm confused. Please clarify how to distinguish between simple and compound sentences when compound subjects or compound verbs have been used.

  • Are you clear about this now?

[1] John and Harry sang well.

[2] John sang well and Harry sang well.

A lower-level distributive coordination like that in [1] can be expanded into a logically equivalent main-clause one, as in [2].

But that doesn't mean that [1] is a compound sentence; it's not. It's a simple sentence with one subject, "John and Harry", and the single predicate "sang well".


Your sentence is simple as it forms one complete idea.

The so-called "compound subject" is termed as "homogeneous" subjects.

As about the definition of compound sentences look this : A compound sentence is a sentence that has at least two independent clauses joined by a comma, semicolon or conjunction.

An independent clause is a clause that has a subject and verb and forms a complete thought. An example of a compound sentence is, 'This house is too expensive, and that house is too small.'
