4 Types of Sentences - Definition & Examples

What Is A Sentence? 

A sentence is a group of words that come together to express a complete idea. It is the main unit of any language.

It always starts with a capital letter and ends with a period (.), exclamation point (!), or question mark (?).

A meaningful sentence contains two important things:

• A subject: who or what the sentence is about.
  
• A predicate: what's happening or being said about the subject.
  

A sentence must contain at least a subject and a verb.

4 Types of Sentences According to Structure

According to sentence structure, there are four main types:

1. Simple Sentences

Compound Sentences
