Usage and Grammar
Q. In certain scenarios (invitations, ads, etc.), our organization sometimes omits the verb: for example, “Complimentary parking available” (with is omitted). If the verb is elided, is it still a sentence requiring a period, or is it a fragment?
A. Although it is a fragment, even fragments require periods when they appear in a paragraph. If a fragment appears apart from other text, however (on a line by itself or in a banner or burst on an invitation or flyer or sign or ad), there is often no need for end punctuation.
