tuy

root. sprout, bud

Tolkien used this root and ones like it for sprouting things for much of his life. Its earliest appearance was unglossed ᴱ√TUẎU in the Qenya Lexicon of the 1910s, where the Ẏ probably represents an ancient palatal spirant [ʝ] or [ç], with derivatives like ᴱQ. tuile “spring, (lit.) a budding” and ᴱQ. tuita- “to bud, burst, burgeon, grow” (QL/96). It also had derivatives in the contemporaneous Gnomish Lexicon such as G. tuil “spring” and G. tuitha- “sprout, spring, gush” (GL/71). In The Etymologies of the 1930s Tolkien gave the root as ᴹ√TUY “sprout, spring” with derivatives like ᴹQ. tuia-/N. tuia- “sprout, spring” and ᴹQ. tuile “spring-time” (Ety/TUY). The root reappeared several times in Tolkien’s later writings with glosses like “sprout” (PE19/54) and “sprout, bud” (VT39/7).
