If a sentence Has two subjects but 1 verb is?

You're describing a sentence with compound subjects and a single verb. Here's how it works:

Compound Subject: This is when two or more subjects share the same verb. They are connected by coordinating conjunctions like "and", "or", or "nor".

Example Sentences:

* The dog and the cat *played* in the yard. (Subjects: "dog", "cat"; Verb: "played")

* My sister or my brother *will* come to the party. (Subjects: "sister", "brother"; Verb: "will come")

* John and Mary *are* going to the movies. (Subjects: "John", "Mary"; Verb: "are going")

Important Note: The verb in these sentences must agree with the plural subject, even though there are multiple subjects.
