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”.
I hear ‘weary’ used in place of ‘wary’, I don’t think I’ve come across the reverse. Drives me crazy though.
