Gnomish

brigli

noun. variation

A word appearing as G. brigli “variation” in the Gnomish Lexicon based on the early root ᴱ√vṛt (GL/24).

Neo-Sindarin: Since I use ᴺS. gwista- “to change, vary” for purposes of Neo-Sindarin, I would update this noun to S. gwistanneth “variation”; compare N. prestanneth “mutation”.
