Hi!
I wonder if there is a word/phrase for "language teaching" in Quenya or Sindarin (I have only found lambengolmë for linguistics, but what I'm looking for is with more of a pedagogical aspect.) Anyway, I've tried to translate it to Sindarin: probably
lam+golthanneth -> lamgolthanneth
but I don't know whether some kind of inflection or sound-change would be needed.
