What’s an expletive, and is it bad? There are several types of expletives, and though some may be considered offensive, others merely signal passive sentence construction or a perhaps desirable vagueness.
Readers of a certain age may recall, during the Watergate scandal, references to “expletive deleted” in discussions of audiotape recordings of conversations between Richard Nixon and certain government officials: Profanity (lots of it) was censored when the recordings were prepared for court proceedings. At that time, “expletive deleted” entered the lexicon as an ironic reference to profanity.
This phrase derives from the linguistic definition of expletive, which comes from the Latin term explere, meaning “to fill”; it refers to a meaningless word. “Expletive deleted” denotes the omission of a potentially offensive word, but that’s not the only usage of expletive.
