ᴱ√GIWI root. “*germinate, impregnate”
A root in the Gnomish Lexicon of the 1910s with various derivatives having to do with pregnancy, such as G. gaiw “pregnant” and G. gioth “germ, foetus, embryon” (GL/37, 39). It also seems to have been the basis for the root ᴱ√QIMI “*woman” in the contemporaneous Qenya Lexicon (QL/77) via G(I)WIMI > GWIM > KWIM; see that root for details. As the basis for female words it was almost certainly abandoned, but I think it may be worth retaining this root for Neo-Sindarin words for pregancy, for which we have no other attested alternatives in Tolkien’s later published writings.
