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”.
This is one of those ones that’s taken on it’s own meaning, unfortunately, if you’re a fan of what it originally meant.
Same with “peruse.” People normally mean browse through a selection, but it originally meant examine thoroughly.
Or “fortuitous” which used to mean purely “by chance” but now means “by happy chance”.
