yáva

noun. fruit, produce

yavanna

feminine name. Yavanna

yava-

verb. to bear fruit

A verb appearing in the form ᴱQ. yavin “bears fruit” in the Qenya Lexicon of the 1910s under the early root ᴱ√ẎAVA having to do with fruit (QL/105).

Neo-Quenya: Since ᴹ√YAB “fruit” survived in Tolkien’s later writings, I think ᴺQ. yav- “to bear (fruit), ✱yield, bring forth, produce” can be retained for purposes of Neo-Quenya.

yava-

verb. to hold

A verb for “hold” in Early Quenya word lists of the 1920s (PE16/133). It is of unclear derivation, but possibly related to ᴱQ. yavin “bears fruit” as suggested by Patrick Wynne and Christopher Gilson.

yávan

noun. harvest, autumn

narqelion

noun. Autumn

silkesse

noun. harvest

A noun appearing as ᴱQ. silkesse “harvest” in the Qenya Lexicon of the 1910s under the early root ᴱ√SḶKḶ that was also the basis for “grass” words (QL/84).

Conceptual Development: The Etymologies of the 1930s updated this root to ᴹ√SALAK+wē for “grass” words (Ety/SALÁK), so I think this Early Qenya word can be updated to ᴺQ. salcessë “harvest”. I would assume this word refers to the product of a harvest = “✱produce”, as opposed to yávië which is the time or act of harvesting.
