# Can't add Emacs tag to question

I added the (existing) tag to this question, but when I save the edit, the tag is automatically removed from the question.

On Code Review, all question must have a language tag. For Emacs code, the language would be .

The [emacs] tag is retired, since it is a synonym of .

• Ok, I've seen now that it redirects to elisp, I got confused because it is still an option for tags when adding a question (8 times used), I suppose for historical reasons. – marcanuy Aug 26 '17 at 17:39
