This comes from the chat, and I’ll be as brief as possible:
How would one go about to add tags that are linked to existing tags, such as mediaeval-latin = medieval-latin?
The above example covers British to American spelling conventions (and I am sure there are more). I was surprised when typing up a mediaeval question and not finding any existing tags for it; then I realised my mistake.
I am sure there are other instances where this would be useful, such as for author names:
plinius-den-eldre could all be linked to the tag
marcus-tullius-cicero and so forth.
Such a system would make it much easier for people of all countries to take part in the discussion; often-times it is hard to remember what the English way of spelling an author’s name is, or remember how a specific word is spelt in American English.
My question thus is: How can we link tags for spelling variants to existing tags?
