Punctuation

Q. In the sentence “The times, they are a changin’” does the period come before or after the apostrophe? Logic would dictate after, but it does not look right aesthetically.

A. Logic wins in this case: the apostrophe is part of the word, not punctuation for the sentence, and therefore it must cleave to the word, ugly or not: changin’.
