G. giothra- v. “to germinate, be conceived” (Category: to Conceive)
A word appearing as G. giothra- “germinate, be conceived” in the Gnomish Lexicon, a verb form of G. gioth “embryo” from the early root ᴱ√giu̯i (GL/39).
Neo-Sindarin: I would update this word to Neo-Sindarin ᴺS. gythra-, verb form of updated ᴺS. gŷth, based on the later sound change whereby iu > ȳ.
