what is main clause and conditional clause

A main clause is a sentence that can stand alone as a complete sentence, containing a subject and a predicate. It expresses a complete thought and makes sense on its own.

Example: I went to the store.

A conditional clause is a dependent clause that usually begins with "if" or "unless." It expresses a condition that must be met in order for the main clause to be true. Conditional clauses are not complete sentences on their own and require a main clause to make sense.

Example: If it rains, I will stay home. (The main clause is "I will stay home."
