A man gives a police officer a photograph of the man who raped the police officer's wife and says:My people know him. He's not with us. Bragged about it, said, well, matched your wife's account.Police officer: How do you know my wife's account?Man: This is only information, man. Shit in the air. I'm sharing with you.(True Detective)1) Is "only" an adverb or adjective here?2) I think it's an adverb because it's without "the" article. But then, considering the police officer's question, what does he mean by that? I don't know more, I can't tell more, or something else?Thanks for your help.
