As a question it does literally translate to “How’s it going?” and then as a response it’s like “It’s going”, but translating common idioms like this completely literally word-by-word doesn’t really make sense. It’s sort of interesting to think about for the same reason that all idioms are interesting, but it’s not very helpful when it comes to translation.

Am I the only one that answers, "how's it going?" With "it goes."?

Because I definitely do that. I'd expect that to be a common idiom in any language. Somewhat surprised to read this exchange seeming to suggest otherwise.

But the above commenter is saying it doesn't translate 'literally' to that, but rather, that is the equivalent meaning.

The 'literal translation' would be translating word-by-word, which by definition isn't going to work for idioms:

> idiom > > A group of words established by usage > as having a meaning not deducible from > those of the individual words

I don't disagree with you, and in fact I believe the point of the GP to be exactly this -- these idioms' literal interpretations are a bit nonsensical. I was merely trying to point out that I think you two agree.
