1) BREATH/BREATHE
When you need to breathe, you take a breath. “Breathe” is the verb, “breath” the noun.
2) BRING/TAKE
When you are viewing the movement of something from the point of arrival, use “bring”: “When you come to the potluck, please bring a green salad.” Viewing things from the point of departure, you should use “take“: “When you go to the potluck, take a bottle of wine.”
3) BUILD OFF OF / BUILD ON
You build on your earlier achievements, you don’t build off of them.
4) BUMRUSH / BUM’ S RUSH
A 1987 recording by the rap group Public Enemy popularized the slang term “bumrush” as a verb meaning “to crash into a show hoping to see it for free,” evidently by analogy with an earlier usage in which it meant “a police raid.” In the hip-hop world to be “bumrushed” (also spelled as two words) has evolved a secondary meaning, “to get beaten up by a group of lowlifes, or ” bums”. However, older people are likely to take all of these as mistakes for the traditional expression “bum’s rush,” as in “Give that guy the bum’s rush,” i.e. throw him out unceremoniously, treating him like an unwanted bum. It was traditionally the bum being rushed, whereas in the newer expressions the bums are doing the rushing. it’s good to be aware of your audience when you use slang expressions like this, to avoid baffling listeners.
Side note: Britons laughed themselves silly when they saw Americans wandering around in sportswear with “B.U.M.” plastered in huge letters across their chests. “Bum” means “rear end” in the U.K.
5) BUTT NAKED / BUCK NAKED
The standard expression is “buck naked,” and the contemporary “butt naked” is an error that will get you laughed at in some circles. However, it might be just as well if the new form were to triumph. Originally a “buck” was a dandy, a pretentious, overdressed show-off of a man. Condescendingly applied in the U.S. to Native Americans and black slaves, it quickly acquired negative connotations. To the historically aware speaker, “buck naked” conjures up stereotypical images of naked “savages” or—worse—slaves laboring naked on plantations. Consider using the alternative expression “stark naked.”
