As far as the Stack Exchange framework is concerned, you can use just about anything for a tag, and philosophy sounds like a reasonable subject area.
However, the question volume for the classical-chinese tag is pretty low. Currently, there are 17 questions from the last six months. To me, that doesn't seem like enough questions to motivate more precise tags....
We can/should only consider migration when:
the question is off-topic or received poorly here, AND
the question would be welcome at another site, AND
the question is not older than 60 days (otherwise migration is impossible).
While a question may be simultaneously on-topic at multiple sites (e.g. Marvel movies at both Movies.SE and SciFi.SE), there are ...
My opinion: Yes, tags really need to be streamlined! However, users are not going to naturally think of the word "tech" when they're asking questions about IME, fonts, etc.
If a question is poorly tagged, there are often additional issues like poor titles, spelling and grammar errors, or it being off-topic yet not (yet) closed. So they're often ...
tl;dr [politeness] makes for better UX
I think creating a brand new tag is probably unnecessary, as we already have a few that are more or less viable, and it might confuse people who used them in the past.
I suggest to examine what we have:
etiquette: the customary code of polite behaviour in society or among members of a particular profession or group.
For structure, I edited many of these manually. The structure was sometimes used for other things, like complement, or even just used seemingly at random.
After checking, I merged the remaining structure questions into sentence-structure. I don't intend to create a synonym, as other aspects of Chinese also have structure (e.g. paragraph structure, ...
How is the tag currently used
It seems the tag is used to loosely identify questions about:
specific terms (then terminology might be fine)
sets of words, as opposed to one single word (then usage, meaning, difference, might be fine according to the actual content of the question)
difference in usage between one or more words, in which case difference or ...
I think you're quite right:
definition a statement of the exact meaning of a word, especially in a dictionary.
That's a fairly strong argument for adding the synonym definition -> meaning. Done and merged too. (30 July 2020)
It seems like we should also merge I've now merged cc-cedict into meaning. As I think cc-cedict is broader (encompassing ...
I went ahead and did it: there's now only the spoken tag. I don't think this is remotely controversial. Off the top of my head, I created the excerpt
For questions about spoken Chinese (aka "oral Chinese" or "verbal Chinese"); consider also the [pronunciation] tag.
But please edit this if you can improve it or think of a better one.
In most cases, you don't need to do anything. All you need to do is to wait until 03:00 UTC, and tags which don't have any associated questions will be effectively deleted (hidden). This cleanup occurs every day.
If the tag gains an associated question, the tag needs to be edited out of the question, and the next cleanup cycle will trigger a soft-delete.
Okay, I merged them, and changed the tag wiki (feel free to edit this to something better):
For questions about measure words and classifiers (量词), e.g., 个, 双, 张
I'm confident that few people (if anyone) will object to me merging these tags. I feel it's clear from the examples that they're used interchangeably. However, I don't know for sure whether to ...
