A sentence is a group of words that expresses a complete idea or statement. A sentence starts with a capital letter and ends with a punctuation mark, like a period, question mark, or exclamation point. It typically includes a subject and a predicate.

A sentence must contain a subject and a predicate. The subject must contain a noun or nominal word, and the predicate must contain a verb. A sentence can be as simple as a noun and a verb. Example: Birds fly. The subject can contain more than a noun, and the predicate can contain more than a verb.

A sentence is a set of words that makes complete sense. It contains a subject and a predicate. The subject is what the sentence is about, and the predicate tells something about the subject. Understanding sentences is crucial to excellent writing and communicating effectively.
