I'm aware of the existence of [auto-antonyms/contranyms](https://en.wikipedia.org/wiki/Auto-antonym), but I'm looking for something that seems to be the opposite: a situation in which either word in a set of antonyms results in the same meaning. To be clear, a contranym requires antonymous homographs; I am searching for two *distinct* words that are antonyms but convey the same meaning in context. For example, the following sentences mean the same thing:

* How is your homework ***coming***?
* How is your homework ***going***?

The only other example I can think of at the moment is "slow ***up/down***", although there are probably others. (I keep telling myself to write them down as I come across them, but that's a separate issue.)

Additionally, I recognize that there may be a subtle difference in connotation that I'm missing. In the situations I've presented, do the two words mean *exactly* the same thing, or is it inappropriate to use on in certain cases? To me it has always just been the one that comes more naturally in speech, but I believe I use the coming/going example both ways equally as often.

**Edit:** I should state that I'm wondering if a term for such a situation exists; I am not searching for more examples, although those are welcome!
