A simple sentence is a sentence that contains only one independent clause. This means it has a subject and a verb, expressing a complete thought. For example, in the sentence “The cat sleeps,” “the cat” is the subject, and “sleeps” is the verb. Simple sentences can also include modifiers, such as adjectives or adverbs, but they do not have any dependent clauses. Simple sentences are useful for clear communication, as they convey ideas directly and without complexity. They can be combined to form compound sentences, but each simple sentence stands alone. For instance, “The dog barks” and “The cat sleeps” are both simple sentences that can be linked with a conjunction to create a compound sentence.
