What is a simple sentence?

A simple sentence is a sentence that contains a single independent clause.

In grammar, a clause is a group of words that contains a subject and a predicate. The subject is the word that indicates what a sentence is about or who or what is performing an action. A subject can be a noun (car, Tom), a noun phrase (short book, green apples), or a noun substitute (you, they). The predicate is a word that indicates what the subject is doing. A predicate is a verb (runs, is) and the words that govern or modify it (fast, hungry).

A simple sentence contains only a single clause that stands alone and makes grammatical sense. A simple sentence has only one subject and one predicate, as in Tom is hungry.

A simple sentence can also have a compound subject (two or more subjects doing the same action), a compound predicate (two or more actions being performed), and modifiers that describe the subject or predicate (such as adjectives, adverbs, and direct objects). Because it has only one clause, though, it is still a simple sentence.

Why are simple sentences important?

The first records of the phrase simple sentence come from around 1669. It combines the word simple, meaning “uncomplicated,” and sentence, meaning “a grammatical unit of words that expresses an independent idea.” Simple sentences are the most basic sentences you can use in English.

We use simple sentences frequently in English, especially to make an idea easier to understand. Understanding what simple sentences are will help you tackle more complicated sentence structures, such as compound sentences and complex sentences.

Did you know ... ?

Simple sentences don’t have to be short. They can be long, especially if you get creative with adjectives, as in The big, ugly, scraggly dog hungrily ate the half-full can of baked beans.
