Please state in which country your phrase tends to be used, what the phrase is, and what it should be.
Example:
In America, recently came across “back-petal”, instead of back-pedal. Also, still hearing “for all intensive purposes” instead of “for all intents and purposes”.
It’s “I didn’t taste it, let alone finish it.” not “I didn’t finish it, let alone taste it.”. Not those exact words, of course. People get it wrong more often than not IME. The wrong version never makes sense, and it always trips me up.
Oh man, “let alone” is severely misused. Good one!
Don’t think I’ve seen that myself, but that would be pretty fucking annoying for sure.
