A word appearing as ᴱQ. qilya- “adorn, embellish, colour” in the Qenya Lexicon of the 1910s under the early root ᴱ√QILI (QL/77).
Neo-Quenya: I would retain ᴺQ. quilya- in the senses “to colour, embellish” for purposes of Neo-Quenya, but for “adorn” I would use the later verb netya- (VT47/33). In the “Neologism of the Day” (NotD) series on the Vinyë Lambengolmor Discord Server on 2023-04-30, Luinyelle suggested ᴺQ. quilya- might also be used as the verb for “✱to paint”.
