What is the purpose of history? Isn't there any other tag that would, even partially, be used instead of history? For example, the history of a word is its etymology; if I am asking for the etymology, I use etymology, not history.
I think my question What is the historic process for converting vulgar words into simply rude words? fits a tag of history. The question is asking about more than the history of a specific word but rather an entire group or class of words. The language-evolution tag was apt so I also chose it.
I am not strongly attached to any of the tags and would be happy with any decisions so long as the tags themselves get a good description of what should be in that category. If, for instance, the etymology tag's wiki told me that it was most appropriate for the type of question I had asked I would have done so.
