Overview

A simple sentence — sometimes called an independent clause — is a grammatical unit that contains a subject and a predicate and expresses a complete thought. In English it follows basic rules of syntax and grammar. Despite the name, a simple sentence can include more than one word in its subject or verb phrase; it simply has one independent clause.

Core elements

Every simple sentence must have two core parts: a subject and a predicate. The subject names who or what the sentence is about, while the predicate contains the verb and states something about the subject. These parts can be expanded but remain a single clause.

  • Subject — single noun, pronoun, or a compound subject (e.g., "The cat" or "Tom and Jerry"). See subject.
  • Predicate — contains at least one verb and may include objects or modifiers. See verb.

Examples and forms

Simple sentences appear in a variety of lengths and styles. Short examples include:

  • "Birds fly."
  • "She laughed loudly."
  • "Tom and I went to the store."
  • Imperative forms often omit the explicit subject: "Stop." (subject "you" is understood)

A simple sentence differs from a compound sentence (two or more independent clauses joined by a conjunction or punctuation) and from a complex sentence (an independent clause plus one or more dependent clauses). A simple sentence remains a single independent clause even when it contains a compound subject or compound predicate.

Importance and use

Simple sentences are foundational in language learning and in clear writing. They establish basic facts, commands, or descriptions and are often used for emphasis or clarity. Writers and teachers use them to build more complex structures while maintaining grammatical correctness and readability.
