A simple sentence contains a subject and a predicate and expresses a complete thought. It is also called an independent clause.
- I like to study in the mornings
- Farida and Fathima play chess every afternoon.
A compound sentence contains two independent clauses (simple sentences) joined by a co-ordinating conjunction (for, and, nor, but, or, yet, so.)
- She tried to speak Hindi, and my sister tried to speak English.
- He danced at the party but his friends did not join him.
