English Grammar/Subject and Predicate/What is a Sentence
The sentence is the basic structure that writers use to make the statements that form a paragraph. It begins with a capital letter and ends in a form of punctuation such as a full stop, exclamation mark or question mark. The sentence uses words to express a complete thought and normally has at least one subject and one predicate.
Pattern 1; Subject-Verb
The simplest sentence pattern is the subject-verb pattern. To complete this pattern, a subject and an intransitive verb, the kind of verb that takes no object, are used.
For example: 1. Birds fly. 2. Fish swim.
Pattern 2: Subject-Verb -Subject Complement
This pattern uses a linking verb (a form of the verb be or verbs such as appear, become, feel, grow, look, make , seem, smell, and sound) to connect a subject to its complement (the word or words that describe the subject).
For example: 1. The pie smells delicious. 2. She is a lawyer. 3. He seems preoccupied.
