Understanding the foundational structure of an English sentence is the key to clear communication. Every complete sentence relies on two primary pillars: the subject and the predicate. By mastering these, you gain the ability to analyze, write, and refine sentences with precision.

Defining the Subject and Predicate

The subject is the anchor of a sentence. According to the Cambridge Dictionary, it represents the person, place, or thing being discussed or studied. Meanwhile, the Collins Dictionary clarifies that the subject is the noun group that performs the action described by the verb. In contrast, the Merriam-Webster Dictionary defines the predicate as the portion of a sentence that provides information, states an action, or describes the state of the subject.

Types of Subjects

Subjects generally take the form of a noun or pronoun and can be categorized into three distinct types:

  • Simple Subject: Has only the subject.
  • Complete Subject: Has a subject with a modifier.
  • Compound Subject: Two or more subjects joined with the help of a conjunction.

Types of Predicates

Because the predicate describes what the subject is doing or being, it is built around verbs. These also follow a three-part classification:

  • Simple Predicate: Has only a verb.
  • Complete Predicate: Has verbs with a modifier.
  • Compound Predicate: Two or more verbs with a conjunction.
