Table Of Content

There are different categories in which each and every sentence that you write or speak falls. And having a good understanding of these categories helps to enhance the writing skills of one. The knowledge of various types of sentences helps you to deliver your ideas clearly and with variety. Sentences are not just the line full of words they are more than that. They carry purpose, tone and structure. Sentences are of different kinds some of them make statements, ask queries, provide orders and some of them are full wall of emotions.

Keep on reading this guide as it covers every sentence type, provides real examples and some tips to make your writing more effective and meaningful. The way how you see a sentence now and after reading this will change completely. 


What Are the Types of Sentences?

There are four types of sentences when it comes to purpose: declarative, interrogative, imperative, and exclamatory. Each type has different functions relating to communication: telling story, asking questions, giving orders, or stating strong emotions. In addition to the four-purpose classifications above, sentences fall into a number of other classifications based on how they are structured (simple, compound, complex, and compound-complex sentences), which are detailed later in this guide. The two form of classification of sentences is used to provide two different things. Purpose of sentence is delivered with the help of purpose based classification and structure of sentence is being known with the help of structure based classification.

Declarative Sentences: Definition, Examples & Tips

Just about all of what we read and write consist of declarative sentences, and they do the bulk of the work. They don't ask, they command, they exclaim, they simply say something - that's why they're so ubiquitous in books, articles and chatter. Before talking about tips and examples lets have a look at the definition of declarative sentence.

What Is a Declarative Sentence?

Information is delivered with the help of declarative sentence. A declaratory sentence makes a statement, an opinion or an idea. This is the main form of sentence you will find in regular writing (book or text). Declarative sentences have no special punctuation, tone, and always have a subject and verb. The use of declarative sentences is widespread throughout as these are the most frequent type of sentence used in language use and are the most common to learn and use properly.

Examples of Declarative Sentences

Once you start to compare the other types of sentences to the declarative sentences, it becomes easier to see that they're declarative and have a matter of fact feeling. For you different types of sentences with examples of Declarative sentences are mentioned below to help you grasp the things easily:

  • The library will be closed on weekdays at 8pm.
  • In her spare time she loves to paint scenes of landscapes.
  • Water boils at 100 degrees Celsius at sea level.
  • My brother is going to college to get a degree in engineering.

See how every sentence example only provides information and doesn't inquire, command or exclaim anything; and that is the real mark of a declarative sentence example.

Writing Tips for Declarative Sentences

Although declarative sentences may appear easy to read, there are a few little habits which will help you to read them more smoothly and to avoid them being dull or dull reading.

  • Maintain the consistency of verb and subject positions (so the subject comes before the verb) to make the sentence understandable.
  • Avoid packing a lot of information into one sentence; if this is not possible then segment these into line breaks.
  • Use verbs and as specific and as powerful verbs as possible – verbs such as is/has are much more common and less specific.
  • Avoid monotonous writing, applying short, medium and long sentences.

Syntactically, these little nuggets of behaviour, will help you to make your declarative sentences elegant, not a bit flat, or even predictable.


Interrogative Sentences: Definition, Examples & Tips

Questions encourage inquiry, they become conversation starters, and they bring a reader into whatever you are writing: interrogative sentences are intended to do all this! Their way of presenting information is different from that of declarative sentences, not only in form, but also in the presence and nature of the punctuation.

What Is an Interrogative Sentence?

It is very important for one to have the clear knowledge about the traits of the word orders and punctuation devices used because interrogative sentences are known for their word order and punctuation. The sentence that asks questions from you and have a question mark in the end are clearly called interrogative sentences. Words such as who, what, when, where, why, how, do, does makes the starting of such type of sentences. If you've ever pondered upon the question what are the four types of sentences, the interrogative sentence is one that is every easy to spot because of its use of the question mark at the end and its use of the verb before the subject, particularly when defining an action ("Does she see him?").

Types of Interrogative Sentences

Not every question is created equal and categorizing interrogative sentences gives us an appreciation of the versatility of this sentence type. There are four types of interrogative sentences: 

  1. Yes/No questions: A question which can be answered with a simple yes or no. (Did you complete the report?)
  2. Wh-questions: Start with question words such as; who, what, when, where, why, how. (Why did the meeting have to be postponed?)
  3. Choice questions: Provide 2+ options. (Would you like tea or coffee?)
  4. Tag questions: The use of a short question at the end of a statement. Really, it's a cold day what?

Questions can have different meaning and have same formal structure are clearly visible in the above mentioned 4 sub categories.

Examples of Interrogative Sentences

Definitions are not enough to convey the differences between types of questions, real examples clarify this much more.

  • Have you ever been into Paris?
  • At what time will the train arrive?
  • Why do birds migrate to cooler places in winter?
  • Do you plan to attend the party tonight?

They all have a question mark in them, and that indicates that they are asking questions, hence they're interrogative sentences.


Imperative Sentences: Definition, Examples & Tips

Comans, requests, instructions are grammatical subject of imperative sentence. This is a special type of sentence since it frequently omits its subject altogether and depends on its context for its meaning.

What Is an Imperative Sentence?

An imperative sentence can be recognized at a glance if there is some reason why the subject is going out of the sentence. Instructions, requests and commands are made by imperative sentences. Subjects are not being used by this type of sentences. You is the subject in such sentences. For instance, in “Turn off the lights” you understand the you, without actually saying it. When considering different types of sentences, imperative sentences is the most different type of sentence when considering the tone of the sentence based on the meaning. They can share the same grammatical form, but have very different inflections and connotations.

Examples of Imperative Sentences

Following is a list of imperative sentences that varies in whether the sentence is polite, urgent or firm, depending on the wording.

  • Be sure to return your assignment by Friday.
  • Turn left at the next intersection.
  • Be sure to lock the door!
  • Pass me the salt, please.

Every imperative sentence you encounter tells someone to do something, as shown by each example above.

How to Identify Imperative Sentences?

By following a few short clues, you can identify if a sentence is imperative, even if it doesn't sound or be punctuated in the typical manner.

  • Search for the subject that has gone missing or is not explicitly stated, but presumed (typically "you").
  • Determine whether any sentence provides a direction or command, a request, or an instruction.
  • It may finish with a period–or an exclamation mark–depending on "urgency.
  • Ask: does the sentence tell someone to do something? If yes, it's likely imperative.

With the help of this checklist you can easily find out the imperative sentences in writing and even in the conversations.


Exclamatory Sentences: Definition, Examples & Tips

Exclamatory sentences are for expressing emotion, and this is a place where emotion must have an outlet—namely, in writing. They add passion, zest or urgency to ordinary remarks and instantly alter their meaning for the reader.

What Is an Exclamatory Sentence?

This sentence type is about the impact punctuation can have on emulsions, and only punctuation alone can make such a difference! A sentence that uses exclamation marks, and expresses excitement, surprise, anger/joy, is an exclamatory sentence. Used in creative writing, casual conversation, dialogue, these sentences add energy and personality to writing. In a description of 4 types of sentences with examples, exclamatory sentences can be identified easily as they are usually the most intensive type of sentence and they end with an exclamation mark.

Examples of Exclamatory Sentences

Saying these examples out loud will show just how potent an exclamation mark is when added to the representation.

  • That was an amazing show!
  • I am amazed at how we achieved a championship!
  • Boy, that did hurt!
  • This meal has been the best and best I've ever had here!

The sentiments in each of the sentences above is powerful, and instantly takes it beyond a simple statement, and into the realm of emotion.

Tips for Using Exclamatory Sentences

The use of exclamatory sentences is of great emotional significance, which is why it is just as important to master than to write an exclamatory sentence correctly.

  • In academic writing use them sparingly – don't overuse.
  • Avoid using exclamation points for habitually made statements.
  • Use of exclamation can make characters come to life in dialogues and in story.
  • Don't use several exclamations (!!!) in formal or scholarly writing.

When used carefully, exclamatory sentences can add vitality to your writing, but not overwhelms your reader.


Simple, Compound, Complex & Compound-Complex Sentences (Structural Types)

Purpose is not only the way to classify a sentence, structure is also equally important. When we talk about types of sentences simple compound and complex we talk about the way in which clauses are joined together instead of what is being communicated by the sentence.

Simple Sentences

Here is the building block of the English grammar with one single complete sentence and nothing further attached to it. A simple sentence has one independent clause which has one subjective and one verb.

Example: The dog barked loudly.

This is the most independent of all sentence structures, as it contains one idea in one sentence.

Compound Sentences

Combos of two contiguous sentences are considered to form a new sentence type and have a different set of connecting words. An independent clause can be joined with one or more independent clauses by an independent coordinating conjunction (and, but, or, so, yet) or by a semicolon to create a compound sentence.

Example: I would like to go for a walk, but it's raining.

These are both sentences on their own, and this is a characteristic of a compound sentence.

Complex Sentences

More details are added in a simple sentence by a dependent clause. It is done to give explanation to simple sentence. Sentence that has one independent and one dependent clause and is joined with the help of conjunctions like because, although, since or when are called as complex sentences.

Example: Although she was tired, she finished the marathon.

In complex sentence a dependent clause cannot stay alone as in the case of compound sentence.

Compound-Complex Sentences

When a category contains all structural elements in one sentence it is the most informative of all categories. This is a hybrid compound-complex sentence that is made up of two independent and at least one dependent clause.

Example: Because the traffic was heavy, we left early, and we still arrived on time.

Writers can add rhythm and variety to their sentences by having the clear knowledge about these different types of sentences in English. By this you can avoid being dependent on one structural pattern.  

Quick Comparison Table: Structural Types
 

Structure

Clauses

Example

Simple

1 independent clause

She reads every night.

Compound

2+ independent clauses

She reads every night, and she writes every morning.

Complex

1 independent + 1 dependent clause

She reads every night because it helps her relax.

Compound-Complex

2+ independent + 1+ dependent clause

Because she loves stories, she reads every night, and she writes every morning.

Common Mistakes Students Make with Types of Sentences

Very much aware of Grammar but sometimes still stumble on grammatical problems when it's time to write. This section goes through the most prevalent mistakes students make in their work and how this can be quickly corrected.

Top 6 Common Mistakes

The most common type of sentence errors have to do with punctuation or clause patterns and figuring out the reason for each error is much easier to avoid it. The knowledge of sentence structure in the English grammar is learning to detect these when they occur first; and prevent them until they become well-acquired.

Mistake

Correct Version

Using a period after a question ("Where are you going.")

Where are you going?

Treating a fragment as a complete sentence ("Because it was late.")

Because it was late, we went home.

Overusing exclamation marks in formal writing ("This report is important!!!")

This report is important.

Confusing imperative with declarative ("You should close the door.")

Close the door.

Joining two independent clauses with just a comma ("She left, he stayed.")

She left, and he stayed.

Mixing sentence types without proper punctuation ("Can you believe it.")

Can you believe it?

While the following errors are typical for students learning the four sentence types, the pattern each type makes is easily recognized, which facilitates students' self-editing down the road.

Types of Sentences: Tips for Better Writing

After you are able to recognize the differences in kinds of sentences, the next step is growing familiar and adept at developing your own writing style. An effective writer is not afraid to vary sentence structures or type on purpose, in order to direct the pacing, emphasis, and tone of a passage.
