Punctuation

Q. In a chapter title in a book, should I drop the apostrophe? ’Till Death Do Us Part, or Till Death Do Us Part?

A. Dropping an apostrophe from a word is not optional; it’s part of the word. Perhaps you are confused about the word till, which does not have an apostrophe; it’s a complete word. You might be thinking of ’til, which is a shortening of until.
