Is the following sentence missing semicolons or commas? If so, where?: The hill was covered with wildflowers it was a beautiful sight.
The hill was covered with wildflowers; it was a beautiful sight.
Here, we must use a semicolon instead of a comma because independent clauses that are joined by commas must have a coordinating conjunction in between them (coordinating conjunctions- for, and, nor, but, or, yet, so). Joining two independent clauses with a comma but without a coordinating conjunction results in a comma splice.
Semicolons do not need coordinating conjunctions.
I love cake, but my sister prefers cookies. (a comma was used along with a coordinating conjunction to combine the two independent clauses).
I love cake; my sister prefers cookies. (a semicolon was used without a coordinating conjunction to combine the two independent clauses).
