ᴱ√ITI¹ root. “peck, bite (of flies), annoy”
A root in the Qenya Lexicon of the 1910s glossed “peck, bite (of flies), annoy” with derivatives like ᴱQ. itisya- “to itch, irritate” and ᴱQ. itse “small fly” (QL/43). The Gnomish word for “fly”, G. sitha, was probably related (GL/68). There are no signs of this root in Tolkien’s later writing, and the word for “fly” became Q. pupso/S. budhu (PE19/101). However, I think it is worth postulating a Neo-Eldarin root ᴺ√ITITH to salvage early Qenya words for itch and annoy.
