First of all, you need to know what a compound sentence is. It is a sentence which contains at least two independent clauses. Having that in mind, here is an example of such a sentence containing words sharecropper and windswept:
<em>The sharecropper worked in the windswept fields the entire day and then went home to eat some food.</em>
There are two independent clauses here: 1. the sharecropper worked in the windswept fields + and + 2. then (he) went home to eat some food.
