The Quenya word for “fruit”, most notably as an element in the name Yavanna “Giver of Fruits, (lit.) fruit-gift” (S/27; SA/yávë; PE17/93) and derived from the root ᴹ√YAB of similar meaning (Ety/YAB).
Conceptual Development: This word dates back to ᴱQ. yáva “fruit, produce” in the Qenya Lexicon of the 1910s under the early root ᴱ√ẎAVA, already an element of Yavanna’s name (QL/105). The word reappeared as ᴹQ. yáve “fruit” in The Etymologies of the 1930s under the root ᴹ√YAB of the same meaning (Ety/YAB). In Quenya Prayers of the 1950s, the word appeared as yáva, yávë and yave (VT43/26-28).
yávë noun "fruit" (YAB), cf. Yavanna. Early "Qenya" has yáva (LT1:273); the form yava turns up even in later material (VT43:31)
