True. A sentence is a group of words that expresses a complete thought, and typically begins with a capital letter and ends with a punctuation mark such as a period, question mark, or exclamation point. To determine if a group of words is a sentence, you can check if it has a subject (who or what the sentence is about) and a predicate (what the subject is doing or what is being said about the subject). If all these elements are present and the sentence begins with a capital letter, then it is a complete sentence.
