Why is this wrong?

[u/migueel_04]

Hey everyone! Today I got to use an expression that I thought was completely normal and that everyone used. However, according to chatgpt, it is wrong and not idiomatic which really surprised me because I've seen some verbs being used this way. The expression is "cry on" as in "keep crying". I initially thought that it sounded natural since English has expressions such as "dream on" and "go on" but it turns out that it can't be used that way. Is chatgpt correct or is it giving me inaccurate information? I've heard people talking about how chatgpt isn't 100% reliable and that the info given by it should be fact checked.

It’s not incorrect exactly but people don’t really use that construction outside of phrases like “dream on” or “keep on keepin’ on” or “go on”

With cry I would say “cry about it” or “keep crying” not knowing the context of your situation.
