How to Identify Subjects and Predicates
Learning how to identify subjects and predicates will help students and employees comprehend sentences and avoid sentence fragments and run-ons in their writing.
Definition: The simple subject is the common noun, proper noun, or pronoun that the verb acts upon. The subject is the “do-er” or the “be-er” of the sentence. It tells whom or what the sentence is about. When additional words help name or describe the simple subject, this is known as a complete subject.
A nurse assisted the patient. (nurse)
The police officer helped at the accident. (police officer)
How to Identify Sentence Subjects
The simple subject is usually found at the start of a declarative sentence. To find the simple subject of the sentence, first identify any prepositional phrases and eliminate the nouns and pronouns found in these phrases from consideration. The simple subject of the sentence is not part of a prepositional phrase. Frequently, in imperative sentences, the simple subject, “you,” is implied (suggested, not stated).
Definition: The simple predicate is the verb that acts upon the subject of the sentence. It does the work of the “do-er” or the “be-er” of the sentence. The simple predicate shows a physical or mental action or it describes a state of being. When additional words help describe the simple predicate, this is known as a complete predicate. The complete predicate consists of the rest of the sentence other than the subject.
Michael hurt his hand. (hurt)
He thought of an idea. (thought)
She was a nice lady. (was)
An angry man tried to run me off the road.
How to Identify Sentence Predicates
-To find the simple predicate, first identify the subject and ask “What?” The answer to this question should be the predicate.
-The simple predicate usually follows the subject in a sentence. However, it can be placed before the subject in a question (Was it your mother’s purse?), in an implied (suggested, not stated) sentence (Look out!), or in a phrase or clause at the beginning of a sentence to add special emphasis (Even more interesting was the fact that she knew it would probably rain).
