A noun appearing as G. gioth or giwth “germ, foetus, embryon” in the Gnomish Lexicon of the 1910s derived from the early root ᴱ√giu̯i [GIWI] which was the basis for a number of words having to do with pregnancy (GL/39), where iu to io as usual in Gnomish.
Neo-Sindarin: I would adapt this word into Neo-Sindarin as ᴺS. gŷth, using the later sound change whereby iu > ȳ.
