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”.
TIL just because some people use nauseous to mean nauseated, you don’t know just from looking at them who’s who, so better use nauseated just in case to be safe.
