N. tuia- v. “to sprout, spring; to swell” (Category: to Sprout, Bud, Blossom)
A verb appearing in its [Noldorin] infinitive form tuio in The Etymologies of the 1930s under the root ᴹ√TUY “spring, sprout”, the cognate of ᴹQ. tuia “sprouts, springs” (Ety/TUY). Under the root ᴹ√TIW “fat, thick”, Tolkien said the verb tuio meant “to swell” and was cognate to ᴹQ. tiuya- (Ety/TIW). I suspect it was the result of a blending of these two roots and meanings: “sprout, spring” when applied to plants and “swell” otherwise.
Conceptual Development: The Gnomish Lexicon of the 1910s had the similarly-derived G. tuitha- “sprout, spring, gush”, likely based on the early root ᴱ√TUẎU (GL/71; QL/96).
