An expletive is a swear word. Think of your own examples.
"Every other word that he says is an expletive." "It is easier to use an expletive than to think of an appropriate word." "Naming your dog after an expletive and yelling it in public is not a good idea."
no
Stop playing that *expletive* game, you *expletive* nine year old. Oh wait, you don't know what that word means because you're *expletive* NINE YEARS OLD!
Euphemistically commenting:"I expletive hope he expletive chokes on those expletive pretzels."Expletive meaning "curse word" :"Every other word that he says is an expletive.""It is easier to use an expletive than to think of an appropriate word.""Naming your dog after an expletive and yelling it in public is not a good idea."Also(for the meaning, added merely to fill out a sentence or line, or give emphasis)"The speech was padded with expletive remarks and comments."(given the popular connotation, the other meaning for the term is rarely used)

False. An expletive may or not be introductory in nature, and may or may not be followed by an adjective (I don't know why you say THE adjective; it sounds as if you are talking about a specific sentence that you haven't showed me). For example, the word damn can be used as an expletive, all by itself. Damn! This would normally be an expression of displeasure. Previous answer is correct. An expletive can be used alone, or as the modifier of an adjective or noun . There is nothing objectionable in the original answer.
