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 think it is common to distinguish between whispering something and saying it out loud or aloud. Like if you say something private in a theatre louder than meant, your date might say, “Shh, you said that out loud.” Otherwise “out loud” would have no place at all as “say” alone would cover this meaning.
You’re right about the saying, but I think that explains the malapropism.
Nope
So, can you clarify the difference between “to say something” and “to say something out loud”?
