In English, six basic structures form sentences. Subjects are generally noun or pronoun phrases. The predicate makes a statement, asks a question, gives a command, or expresses a state of being. A simple subject is a noun or pronoun. A complete subject is the simple subject and any modifiers of the simple subject.
Most subject modifiers are adjectives.
A simple predicate is the predicate verb, being verb, or verb phrase associated with the sentence's subject. A complete predicate is the simple predicate and any modifiers. Predicate modifiers may be adverbs, adjectives, and phrases. A sentence is in inverted order when the predicate precedes the subject. Sentences inverted do not require a comma after the introductory phrase.
