A noun in the Gnomish Lexicon with variants G. gund, hunn and glosses “a boil, pus”, derived from the early root ᴱ√gudh having to do with heat and burning (GL/42).
Neo-Sindarin: Since it seems ᴱ√gudh >> √UR “heat, be hot”, I’d update this word to ᴺS. ordh “boil, pus” < ✱urdā = “(orig.) the product of burning”.
