Not a complicated question for professionals. Please give me something. I have money riding on it.

If it were a single word, I would call it a contronym, or a word that can have reverse meanings depending on context or its function as a noun, adjective, etc. However in this case it is two words, but the point remains:

"Tape off that door so paint won't splash on it." (You actually put tape on)

"I took the tape off." (You actually took tape off)

Is this a joke? Find something to do. Or get the painter who knows how to protect one surface from the paint going onto a nearby OTHER surface, or the Mrs Whomever.........trying to figure out what size rug to buy as she "tapes off" an area on the floor ( like a BORDER ) to delineate the size of whatever that rug will be. OR BE BEST. "tape off an 8' x 10' area rug, under the dining table.." ........ Not large enough? Move the masking tape, and re do the "tape off" to a 9 x 12 size..............................

In short, it's protect or DELINEATE a size and space, isn't it? Yeah.......it is.

Do I get the car? lol as I can't believe I answered the question.

Stupid question really .

Tape off is what the police do to crime scenes. Not to be confused with taper off, which is what happens to online discussions when people get bored.
