Sentences are the basic building block of communication. In your grammar class, you were told that a sentence should express a complete thought.

While this is true, the meaning of the phrase "complete thought" may be vague. For instance, some notices seem to be complete, but we don't generally consider them as sentences.


  • Exit, Danger, 50 mph speed limit

On the other hand, some sentences consist of more than one thought. So, how exactly do you define what a sentence is?

This post will not only answer these question, but also explore the types of sentences and how to identify them. Finally, you'll find out how to use the INK Sentence Counter tool.

What is a Sentence?

A sentence is the largest independent unit of grammar. While it begins with a capital letter, a sentence could end with a question mark, exclamation mark, or a period.

The word sentence came from the Latin word Sentientem, present participle of Sentire. It means to be of opinion, feel, or perceive.

We can define a sentence as a word or group of words that expresses a thought or idea through a statement, question, or exclamation.


  • She is a girl
  • Is she a girl
  • We won!

A sentence usually consists of at least a subject and a verb. Although the subject of the sentence may be hidden, the verb must be visible and present in the sentence.

Types of Sentence Structures and Examples

Structurally, there are four types of sentences. These include the simple, compound, complex, compound-complex sentence.

Simple Sentence

A simple sentence has one independent clause and variable.


  • The cat is sleeping.

Compound Sentence

A compound sentence has more than one independent clause. Also, these clauses are usually joined by some specific punctuation, conjunction, or both.


  • The cat is sleeping, but the dog is eating the bone.

Complex Sentence

Like the compound sentence, a complex sentence also has more than one clause. However, one of the clauses must be independent, while the other/others should be dependent.


  • The dog, which is eating the bone, is happy.

Note that some specific connectors are necessary for clauses of a complex sentence.

Compound-Complex Sentence

A compound-complex sentence combines the feature of a compound and complex sentence in a single sentence. As such, it contains at least two independent clauses and at least one dependent clause.


  • The dog, which is eating the bone, is happy, but the cat is still sleeping.

Functional Types of Sentences and Examples

Functionally, there are four types of sentences. These are declarative, imperative, interrogative, and exclamatory sentences.

Declarative Sentence

A declarative sentence is an assertive sentence that expresses an opinion, makes a statement, or describes a thing. This type of sentence usually ends with a period.


  • Brutus is a smart dog.

Imperative Sentence

In English, we use imperative sentences to make a request or to give orders and directions. This type of sentence usually ends with a period — or under specific circumstances, exclamation.


  • Please stand up.
  • I need you to stand now!

Interrogative Sentence

An interrogative sentence asks a question. Expectedly, sentences in this category end with a question mark.


  • Have you met her?

Exclamatory Sentence

We use exclamatory sentences to convey an overflow of emotion, whether it's happiness, wonder, anger, or sorrow. As a result, this type of sentence ends with an exclamation mark.


  • The pie is ruined!

Break Down Sentence Structure into Elements

At this point, you know that a sentence begins with a capital letter, ends with punctuation, and contains at least one independent clause.

In turn, that clause must contain a subjectand a predicate. The subject describes who or what the sentence is about while the predicate describes what the subject does.


  • Cats sleep.

In the sentence above, the cat is the subject, while the word sleep is the predicate. Also, note that the sentence expresses a complete thought.

Determine the Sentence's Purpose

You can identify a sentence by exploring its function. So, ask yourself what a specific sentence is trying to achieve. Is it explaining something, asking something, giving a command, or exclaiming something?


  • Cats sleep.
  • Stop sleeping!

The first example is a declarative sentence. It explains what cats do. The second sentence, on the other hand, is imperative— conveying an order. Again, note that both sentences express a complete thought.

Consider the Sentence's Construction

Aside from determining the sentence's purpose, you should also assess the construction. With that, you'll know if the sentence is simple, compound, complex, or compound-complex.

For this part, you'll want to identify the number and types of clauses in a sentence.

Check for the independent clauses such as "cats sleep," as well as dependent ones such as "when it rains outside." So when you see a sentence that combines these clauses, you can quickly identify it based on the structure.

  • Cats sleep when it rains outside.

Now, try Identifying the sentence above based on its structure and function.
