Sentences are a logical structural unit of any language. Words, the smallest written unit in any language chained together to form a semantic structure called sentences. Different types of sentences find usage in the English language, used across writers across various domains such as essay writers, web content writers, journalists, copywriters, etc.

 This article takes a look at the four primary types along with some major sub-branches.

Four Major Types Of Sentences 

One of the best ways to understand and analyze any sort of sentence is by examining its structure. Let’s start with one of the most common types of sentences encountered in script or speech, the declarative type.

  • Declarative Sentences

So, what is a declarative sentence? 

The primary goal of declarative sentences is making a statement. The extended definition can be given as any sentence that states or tells the listener something that possesses the attributes of the declarative category. No matter what kind of information the sentence delivers, be it a proven fact or any theory,  if any statement is being made or some information declared, then it is a declarative sentence.

The generic structure of such sentences is as follows:

  • Subject + verb + object  The subject is usually a noun or a pronoun (such as a person, object, location, or any entity); 

The verb is a crucial semantic entity that denotes some action or state of being and can be inflected to indicate tense, mood, or voice; 

And the object is a single or multiple word that’s influenced by the verb.


The boy (subject) lost (verb) his favorite comic (object).

Usually, declarative sentences end with a period. Sentences can be positive or negative as per the intention of the speaker or writer.

People use these sentences to make formal or informal statements and deliver information verbally and in writing. 

  • Interrogative Sentences

What’s an interrogative sentence? 

While a declarative sentence is utilized to share information, its interrogative counterpart intends to enquire and acquire information. By definition, any kind of sentence that asks a question or makes any sort of query can be classified as interrogative and ends with an interrogation mark. When spoken, these sentences have a distinct intonation that rises gradually and indicates an intention to interrogate.

Three main types of interrogative sentences can be found in conventional literature and speech, the Yes/No type, the question word type, and the choice type. And, their structure of interrogative sentences varies as per the nature of the interrogation. 

  • Yes/No Interrogations have a straightforward answer of yes or no. They are formed as Auxiliary verb + Subject +Main verb + Remainder info.
  • Question word interrogatives involve query words such as what, why, where, who, which, how, when, whom, etc., and deliver information as per the question word. Their typical structure involves the question word + auxiliary verb + subject +main verb +remainder
  • Choice interrogations demand an answer that’s in the question itself. The structure is as follows Auxiliary verb +Subject + main verb. 
  • Imperative Sentence

What is the purpose of an imperative sentence? 

The main goal of these kinds of sentences is to command others to do something or give some order.

The order of words and structure of imperative sentences differs from other types. These sentences lack a subject and typically contain a predicate or verb, which is the command, followed by information. 

Imperative sentences lay down command or deliver an instruction. They can be in the form of a long sentence or just consist of a main verb. Imperative sentences typically end with a period but can end with an exclamation if the speaker puts emphasis or emotes.

  • Exclamatory Sentences

Exclamatory sentences denote heightened emotions, surprise, or exclamation. They end with an exclamation mark and are spoken with distinctly emotional intonation (shock, disbelief, excitement, pain)


  • Hey you!
  • High voltage! Do not touch!
  • Get over here!

The exclamation mark plays a significant role in denoting a sentence as exclamatory.

  • It’s snowing. (Declarative)
  • It’s snowing! (Exclamatory)

Other Types of Sentences 

Besides the four major types of sentences, are there any other kinds of sentences in literature? Well, there are. 

Typical examples are Simple Sentences, Complex sentences, and  Compound Sentences.

 Simple Sentences – A simple sentence contains a standalone subject and a verb. It can express a complete thought on its own. A simple sentence need not be short and can even include adjectives.


 The baby was crying for food. There is a subject, and a verb expresses a complete thought. 

Morty and Rick overate and felt sick. Despite there being two subjects and verbs, this sentence belongs to the simple category as it shares a common object and relays a common thought.

Compound Sentences

 A compound sentence has two independent clauses. An independent clause is a component of a sentence with a subject, verb & object and can convey some complete meaning or thought.   A compound is a combination of two simple sentences, or two independent clauses joined together by a conjunction (for, and, nor, but, or, yet, so).


 The shoplifter stole some clothes, so he ran as soon as he saw the police. Both sides of the conjunction have complete sentences. Two independent clauses are compounded together to form a single sentence.

Complex Sentences – 

A complex sentence consists of an independent clause that is connected by one or more dependent clauses. The conditional clause can lack a subject or a verb, or it can have both a subject and a verb but does not express a complete thought.  Complex sentences always have a subordinator (as, since, after, although, when) or relative pronouns (who, which) that link both clauses together.


 After having lunch at The Rainbow Bar & Grill, Tom went to the gym to work out.   The independent clause is  the ‘Tim went to the gym to work out.” The subordinate clause at the start is dependent on the main, independent clause.

Tips To Improve Sentence Construction Skills

  • Read & Write Often

The more you write, the better your sentence construction skills will become. 

Write different kinds of content that give you a chance to practice writing different types of sentences.  Academic writing, recreational write-ups, or online web content, go through various write-ups and note how writers craft different kinds of sentences and imbibe them in your mind. 

Apply the ideas and techniques gathered in your writing and write as much as possible to boost your writing skills.

  • One idea, one sentence

Every sentence in any content should portray an idea and serve some purpose. Unless you are trying to stir emotions or achieve a dramatic effect, never use any extraneous words or unnecessary sentences.

Do not try to fit two different points into one long sentence, even more so if they are entirely unrelated. Omit any digressions and deviations, and write in a way to craft a focused narrative.

  • Don’t distort the main idea.

Convoluted and unnecessarily complicated sentences are a serious no-no. If your audience cannot understand or grasp what you are trying to say to them, rich words and complex sentence structures are of no use. Always make sure that your sentences are as lucid as possible and the idea within easily understandable.
