Sentences: Definition, structure, and Types.

There are four types of sentences for different purposes which are: declarative sentence, imperative sentence, interrogative sentence, and exclamatory sentence.

A sentence starts with a capital letter and provides a complete thought.

There are four different sentence structures which are: simple, compound, complex, and compound-complex.

We have already seen all these four different structures in a different lesson.

You can check it from here.

Sentence Types and Functions with examples:

Declarative sentences (simple sentences): declarative sentences are the most used and common among all the four types. We use them to make statements and state information. This type of sentences ends with a full stop (.).

  • Examples:

Grammarlite.com is a good website to learn grammar.

    • Negative: I do not like chocolate.

I did not eat breakfast this morning.

Imperative sentence: imperative sentences make a request or give a command. Is gives an order and tell us to do something. These types of sentences end with a full stop (.) or an exclamation mark (!).

The 4 Sentence Structures with examples:

Before learning about sentence structures, you have to be aware of clauses.

We have already seen a complete lesson about it.

You can check it from here.

Reminder: a clause is a group of words that contains a subject and a verb. A clause may be either:

An independent clause that provides a complete thought and it can stand by itself as a sentence or a dependent clause (subordinate clause) that can’t sand by itself or provide a complete thought and it’s occur as part of the sentence.

When we look at the sentence structure, we find that there are 4 sentence structures, which are: Simple sentence, compound sentence, complex sentence, and compound-complex Sentence.

Simple sentences: a simple sentence consists of one independent clause.

Examples:

  • I love grammar.
  • English is the most popular language.
  • Grammarlite.com is a good website to learn grammar.

Compound sentences: a compound sentence consists of two or more independent clauses joined by a coordinating conjunction or a semicolon.

There are 7 coordinating conjunctions:

For, And, Nor, But, Or, Yet, So.

You can easily remember them by the term (FAN BOYS).

Examples:

  • I like grammar and john likes math.
  • We work differently; We make it fun.
  • We have to work smart or we are going to fail.

Complex sentences: a complex sentence consists of an independent clause and a dependent clause joined by a subordinating conjunction.

Common subordinating conjunctions: after, before, since, when, where, how, if, although, as, because, that …

Examples:

  • I will get high marks because I prepared well.
  • Since you did not prepare well, you can’t get good results.
  • I met a nice person yesterday who was my childhood friend.

Compound-complex sentences: a compound-complex sentence consists of at least two independent clauses and one or more dependent clauses.

Examples:

  • I like grammar because it’s really important, but john likes math.
  • We have to work smart since we have time or we are going to fail.
