Semicolons to Join Clauses
You should use a semicolon when you’re joining two independent clauses without a connecting word. The semicolon functions, structurally, just like a period. The difference is that the semicolon between the two independent clauses shows they are connected, as illustrated in the following examples:
I am so tired of spending so much money on canned food for my zombie apocalypse hoard; I am pretty sure the grocery store clerks are laughing at me behind my back.
