This is a conversation in the film "A Wish for Christmas", you can download its subtitle on the internet
The boss is talking on the phone:
Boss: Frankly, the way things are going, Christmas is turning into
one big, giant headache. I know. Christmas isn't all it's cracked up
to be. I've tried to make it work. If you don't like it, then maybe
you should talk to him. I have to go. Christmas is not happening. I'm
sorry.
After that, a man says
Man: Uh, ahem, did I hear that correct, boss? Because I got five
employees coming in to work on Christmas, but if it's not
happening…Boss: What? No, no. That's not what I meant. No. It's happening.
My concern is that the sentence "did I hear that correct?" sounds unfamiliar
Because "Correct" is an adjective & is never an adverb.
So, I expect he says "Did I hear that correctly?" "correctly" is an adverb & modify the verb "hear"
However we also have object compliment,
Eg: I painted the house black. "Black" is an adjective and a compliment of the house Source
Besides, we've got this structure "hear somebody/something doing something" in the dictionary
Eg: He could hear a dog barking. I would say "barking" is a compliment of "a dog"
I am not sure if I can say "I hear that correct", in this case "correct" is an adjective and a compliment of "that"
So, Which one is correct?
Do you say
"Did I hear that correctly?" or "Did I hear that correct?"
Best Answer
"Correct" can be used as a flat adverb in certain dialects. In fact, that includes the dialect of American English that I speak. It is pretty informal. You can find plenty of examples of this online:
Some flat adverbs are considered Standard English, some aren't. Given that I can't find "correct" (as an adverb) in any dictionary, it should not be considered Standard English. (Of course, just because it is found in a dictionary does not mean that everyone will find it acceptable.)
The history of why flat adverbs are disliked by prescriptivists is interesting too.
