I was on the cusp of editing the currency tag, which currently doesn't have anything in it's wiki, but decided against it. I assumed that the point of the tag was to discuss the linguistic currency in the sense of "the fact or quality of being generally accepted or in use."
There are 34 questions in the tag currently, most of them seem to be about linguistic currency. There is at least one question that has it tagged for the monetary sense of "words, phrases etc. about a medium of economic exchange."
I personally feel that the site is better served by restricting the tag to the linguistic meaning of currency. So I wanted to double check here: is it worth having a tag for linking questions on the monetary sense of currency?
contemporary-usageis probably a better tag. On the concern of whether a currency/monetary tag is relevant, I don't think that it is. Tags should be about parts of language, not the things that language can describe. (In my opinion, anyways.)
contemporary-usage, for example, I think a fuller wiki description about what the greater restriction from Modern English (also, is this referring to a tag or to something else?) is would be helpful; if it is meant for something specific and different, then my merge suggestion is not good.
