I am not sure if this is the right place to post this question.

First, how to choose the tags when asking a question? If one does not know which tag to use?

Second, what is the difference between tags that look the same? E.g.,

  • elementary-set-theory and set-theory?
  • probability and probability-theory?
  • riemann-zeta and zeta-functions?
  • ...

Now I do not know which tag to use either.

  • $\begingroup$ Reading tag-wikis might help. (Unfortunately, often the tag-wikis are empty.) You can find tag-wiki through the link provided in Michael Greinecker's answer. A shorter tag-excerpt is shown to you as a popup when you write a tag into the tag field (when editing the post). They are also shown if you hover above a tag (in a question containing the tag) with your cursor. $\endgroup$ Apr 23, 2014 at 6:03
  • $\begingroup$ As far as tags for this particular questions (on meta) are concerned, I agree that (discussion) and (support) are reasonable choices of the tags. But why is this tagged (feature-request)? I do not see any feature request in the question. $\endgroup$ Apr 23, 2014 at 6:23
  • $\begingroup$ Having said that I try to follow the descriptions in the tag wikis, I was sometimes in the situation where I was not sure whether choose (elementary-number-theory) or (number-theory). The same goes for elementary-set-theory vs. set-theory. $\endgroup$ Apr 23, 2014 at 6:25
  • $\begingroup$ Some advice on choosing reasonable tags is given also in the answer here: How am I supposed to use tags? $\endgroup$ Dec 4, 2022 at 8:35
