The tag hasn't existed before. As I think it knowing it is important for a learner, I wonder if there is a specific reason that it didn't exist. It even has its own Wikipedia page.


Tags are there to categorize questions so that we can find them, not necessarily to teach learners concepts they should know. People tag questions to the best of their ability, and if a term isn't widely known to apply to a particular type of question, it doesn't get created. Anyone with 300 reputation or more can create tags just by adding them to a question.

It's great that you found a term that captures an aspect of your question - now we should find more existing questions that need that tag. A tag that has only one question attached to it and no description on what types of questions it is used for isn't very useful.

  • Thanks. I just wonder if there is a strong reason for not allowing this specific tag existed sooner. This linguistic feature was taught to me very young and I was unable to understand why people wasn't aware of it – Ooker Oct 29 '18 at 3:05

    @Ooker - "did not exist" does not imply "was not allowed to exist" – J.R. Oct 29 '18 at 7:29
  • @J.R. yes, that why I want to make it clear. "Does not imply" does not imply "was crystal clear to see that" :) – Ooker Oct 29 '18 at 8:22
