- "I could care less" meaning "I couldn't care less"
- "Entrée" meaning a main dish rather than a starter
"I couldn't care less" is a much clearer reference to being at this state of absolute-uncaring.
Regardless, I think this is just a result of people getting lazy with their language... it is not meant to be said in this say, and is properly stated, "I couldn't care less". In the US (can't speak for elsewhere) people just repeat what they think others have said, to convey what they think they understood. This is the source of a lot of language rot.
Another one is the pattern “all X are not Y.” Vs “not all X are Y.”
> “I could care less” is a bastardization of couldn’t care less.
I've come to the conclusion that this bastardization came from the way "--dn't c--" feels in the mouth. Lots of consonant sounds in a row. Drop the "n't" and it feels much better to say, even though the phrase becomes nonsense. You even get a little bonus alliteration.

If people do, what similar turns of phrase would they likewise mangle? "Well done son, I could be more proud", or "I'm completely thrilled, I could be happier", or "I'm at rock bottom, things could be worse".

> A number of language writers have suggested that “could care less” has a sarcastic reading, conveying something like “Ha! As if there were something in the world I could care less about.” There are some American Yiddish-inflected phrases that work this way, like “I should be so lucky!” (meaning “there’s no way I’m ever gonna be that lucky”) or “I should care!” (why should I care?). Even if “could care less” didn’t originate from a sarcastic intent, it matches up well enough with these other forms in the language to help give it staying power.

I particularly like this argument from this second link:
> The argument of logic falls apart when you consider the fact that both these phrases are idioms. In English, along with other languages, idioms aren’t required to follow logic, and to point out the lack of logic in one idiom and not all idioms is…illogical. Take the expression “head over heels,” which makes far less sense than “heels over head” when you think about the physics of a somersault. It turns out “heels over head” entered English around 1400, over 250 years before “head over heels,” however, the “logical” version of this idiom hasn’t been in popular usage since the late Victorian era.
In British English it means “disputable” while in American English it means “hypothetical”.
All of these have in common that they're more less the opposite of "something controversial or worth arguing about", which is the British English.
That is a meaning of "moot", but "hypothetical" is not. The word "another" was probably ill-advised there.
