A compound sentence consists of two or more simple sentences joined by (1) a comma followed by a coordinating conjunction (For, And, Nor, But, Or, Yet, So): The dog barked, and the cat yowled.

Simple sentence + Simple sentence = COMPOUND sentence Two or more independent (simple) sentences joined by a coordinating conjunction (FANBOYS) For, And, Nor, But, Or, Yet, So Tracy cried, and the other children laughed at her. Craig and Liz were competitive, but they just didn’t have what it takes to win.

FOR - is to introduce the reason for the preceding clause AND - joins two similar ideas together NOR - it is not used nearly as often as the other conjunctions. Its most common use is as the little brother in the correlative pair, neither-nor BUT - joins two contrasting ideas together OR - joins two alternative ideas YET - is very similar to 'but' as it also joins two contrasting ideas together SO - shows that the second idea is the result of the first
