Compound Sentences

A compound sentence contains two independent clauses which are joined by a semi-colon, a coordination conjunction (preceded by a comma), or a conjunctive adverb (preceded by a semi-colon and followed by a comma). 

For examples,

• She was sick, so she didn’t come to work.
• Students work hard; they succeed.
• The job was difficult; however, we could finish successfully.

Note:

- There are two independent clauses in compound sentences.
- There is no dependent clause in compound sentences.
