korna

adjective. round, globed

A word in The Etymologies of the 1930s glossed “round, globed” derived from primitive ᴹ✶kornā under the root ᴹ√KOR “round” (Ety/KOR). It likely means “✱round in three dimensions”, as opposed to ᴹQ. rinda “circular”.

Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. korima “round” under the early root ᴱ√KORO “be round, roll” (QL/48).
