Semicolon vs. comma
Generally, I prefer two short sentences to one long one. Still, if you must use a semicolon, you’ll know you’re doing it right if the two parts of the sentence can be independent thoughts, or two complete sentences.
The hack: Think of the semi-colon as a super comma. Maybe inside your head say “Semicolon! Super Comma!” in the voice you’d use for “Super Man!” or “Wonder Woman!” FYI, this hack comes from a super hero copy editor pal who prefers to wield her powers under the cloak of privacy.
