Hi
My dictionaries tell me that cop-out (an instance of avoiding a commitment or responsibility) is slang, but I have seen this compound word being used in our English newspaper and have also heard it used by someone on CNN.
Could you please tell me how the use of cop-out in formal English would sound to your native ears?
By the way, is it slang or just informal?
Thanks,
Tom
I see it as slang, used mainly in casual, spoken English.

Mr. Tom the use of cop-out in formal English
No, it is very informal. It is negative, disapproving.
