The word ᴱQ. itse “a small fly” appeared in the Qenya Lexicon of the 1910s derived from the early root ᴱ√ITI “peck, bite (of flies), annoy” (QL/43).

Conceptual Development: A similar (archaic) word ᴹQ. tsette “fly” appeared in notes on The Feanorian Alphabet from the 1940s (PE22/51). This word is questionable given that while ps and ks were listed among valid initial clusters in Quenya, ts was not (PE19/38, 80).

Neo-Quenya: I would retain the Early Qenya word as ᴺQ. itsë “small fly”.
