A word in the Qenya Lexicon of the 1910s appearing as ᴱQ. auqa “awkward, clumsy (of things); awkward, difficult”, an adjectival form of ᴱQ. auk “a fool, clumsy fellow” (QL/33).

Neo-Quenya: I would retain ᴺQ. auqua for purposes of Neo-Quenya, but mainly in the sense “awkward, clumsy” applicable to both people and things. For “difficult” I would use hraia and hranga.
