Compound Sentence in English Grammar

Compound Sentence in English Grammar


Let’s first discuss about sentence. It is a group of words conveying compete meaning or thought. A complete thought can be conveyed as a statement, a command, an exclamation, or a question.

The basic thing in a sentence is a complete thought. Every group of words can’t be a sentence. The main condition is giving of complete meaning.

  • She hoarded data for her thesis. (Sentence)
  • Studying English at night (Not a sentence)

As we know that sentences have four types structurally. In this article, we are discussing compound sentences. You can study the remaining types like simple sentences, complex sentences, and compound complex sentences in the site of Study English Page.

Definition of Compound Sentence

Compound sentence is defined as a sentence that has two or more than two independent clauses joined by a conjunction or a suitable punctuation mark. More simply, a compound sentence is a combination of at least two simple sentences. Each part of the compound sentence gives a complete thought, but adds more to the meaning in compound sentence.

  • John drives, and Jack teaches.
  • I can speak English, but she can’t speak English.

The above sentences are compound sentences. They have more than one independent clauses joined by conjunctions. You can make two simple sentences from each sentence by omitting the conjunction.

  • She writes articles; I edit them.

This is also a compound sentence. It has two independent clauses joined by a punctuation mark. The two independent clauses can stand alone by themselves if you want to separate them.

  • Formation of Compound Sentences

    There are three basic ways to form compound sentences. Compound sentences consist of independent clauses. To construct a compound sentence, you need to use coordinating conjunction, colon, or semicolon.

    Using Coordinating Conjunction

    Using coordinating conjunction is one of the most common ways to join independent clauses. When independent clauses are joined, a compound sentence is formed.   

    • We can make a peaceful society, and we can destroy.
    • Violence makes the society destroyed, but peace brings happiness.

    Using Colon

    By using colon we can join independent clauses to make a compound sentence. Remember that we use colon when an independent clause explains, illustrates, or paraphrases the previous one.

    • He showed his loyalty: he helped his friend.
    • I have a plan for my near future: I am going to marry.

    Using Semicolon

    Semicolon can be used between independent clauses. It can also be used to replace coordinating conjunction. When a semicolon is used between independent clauses, it will become a compound sentence.

    • She will come tomorrow; I don’t want to meet.
    • I bought an old, cheap, and well-designed car; but now I want to sell.

    Key Points

    Appropriate Punctuation Marks

    Using of punctuation marks is so important to make compound sentences. You need to use appropriate punctuation marks. A comma is used before a coordinating conjunction to join independent clauses. As mentioned earlier in the formation, we use colon and semicolon to join independent clauses.


    • I will give you a letter; you will send him.
    • She will come tomorrow; I will discuss about your problem.


    • I have a plan for you: you should resign from this post.
    • I have a plan for my near future: I am going to visit New York.


    • I like walking early in the morning, but I don’t like running.
    • Ali distributed candies among the students, and the students thanked.

    Using Independent Clauses

    A compound sentence has at least two independent clauses joined by coordinating conjunction, colon, or semicolon. Sometimes, dependent clause is mistakenly used in compound sentence. A sentence that has a dependent clause can’t be a compound sentence.

    • Accountant prepared a bill, and I sent to the manager. (Compound sentence)
    • If the accountant prepares a bill, I will send to the manager. (Not a compound sentence)

    Conjunctive Adverbs

    Conjunctive adverbs are also used to join independent clauses. When a conjunctive adverb is used, it must be followed by a comma and preceded by a semicolon.  

    • Adela loves John; however, John does not love her.
    • You must study hard; otherwise, you will be failed.
