The sentence is a group of words which express a complete thought. The sentence is made up of the following units:
Words. We all know what a word is. Words are made of letters. A word expresses a single idea. This sentence has five words. The study of words and their meanings is called vocabulary. If you have a huge vocabulary, it means you know the meaning of lots of words and you therefore will possess a strong command of the English language. To build your vocabulary, use these exercises.
Phrases. A phrase is a group of words that fall short of being a complete sentence. A phrase may contain a verb but not a subject, or a subject but not a verb. Therefore, a phrase does not express a complete thought.
Clauses. A clause is a group of words which contain both a subject and a verb. Some clauses express a complete thought. Some clauses may be modified to make a sentence. They are called principal clauses. Other clauses do not form a complete idea. They depend on the principal clause to complete their meanings. Theses are called subordinate clauses.

Punctuation of Sentences. Punctuation marks make a sentence more understandable, and they include the full stop, the comma, the question mark, quotation marks, the exclamation marks and a few others. Punctuation marks are like traffic signs: they tell you where to stop, where to slow down, where to accelerate and also where you are.
For example, the comma signals a brief pause, the full stop signals the end of one sentence, and a capital letter signals the start of a new sentence.
Every sentence has a subject and a predicate. The subject of a sentence is what is being spoken about, and the predicate of a sentence is what is said about the subject.
For example, in the sentence: The dog barks. dog is the subject and barks is the predicate. This is an example of a simple sentence.
Sentences are classified in two ways in the English language:
- By purpose
- By structure
When classified by purpose, there are four types of sentences:
The Assertive Sentence
The Imperative Sentence
The Interrogatory Sentence
The Exclamatory Sentence

When classified by structure, there are also four types of sentences. They are:
- The simple sentence
- The complex sentence
- The compound sentence
- The compound-complex sentence

Each sentence needs a subject, that is, it needs something to talk about. What you talk about in a sentence is called its subject. Every sentence also needs a verb. The verb gives life to the sentence. Without a verb, a sentence cannot function. Try making a sentence without a verb.
A verb is part of the predicate of the sentence. To learn more about subjects and predicates of sentences, click here.
