I'm not sure what the locative is there for. It barely even survived into classical Latin. Did it survive into Vulgar Latin? Also, why not use a module?
No, that’s just a relic that I di’n’t know what to do with. Not sure what you mean by module. Since case functions were shared variously in different conjugations, I would rather not make a mother template; my template knowledge is still rather crude.
I meant a Lua module. That way, there wouldn't need to be two parameters, just one would be enough.
I told you, my knowledge of templates is crude. I dun know exactly what an Lua module is, or how to create one. And am not sure what you mean by parameters. Are talking about the digits sandwiched with braces?
It is much more powerful than templates though, and faster too. It can look inside text and search for or replace individual characters. So it could also strip out acute accents and underdots from accented Vulgar Latin forms, which a template can't do.
