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”.
“Chomping at the bit”. It’s champing at the bit. Horses champ.
“Get ahold of”. It’s “get hold of” or, if you must, “get a hold of”
“I’m doing good”. No, Superman does good. You’re doing well.
Wow, this is the first time I’ve ever heard of this one! Good job to you and this thread!
My favorite of these mnemonics (try spelling that from memory) for these arbitrary distinctions was in a movie that had some evil lords in it. The father way telling the son,
“Pheasants are hung, peasants are hanged.”
