Semicolons do NOT separate dependent clauses; commas can, as seen in the following sentence. Semicolons CAN separate independent clauses, as seen in the previous sentence. Semicolons are also useful in a list, if the items normally separated by a comma already contain commas. We visited London, England; Paris, France; and Rome, Italy.
Friends, stop using semicolons incorrectly. It makes you look like an idiot. If you don't know how to use one, don't. There are ways to survive without this glorious comma-and-colon-combination, though we all know I prefer to survive with it.
Love and Semicolons,
