An adjective for “female” in The Etymologies of the 1930s, derived from the root ᴹ√INI “female” (Ety/INI).
Conceptual Development: In Early Qenya Word-lists of the 1920s, Tolkien gave a similar form ᴱQ. qinya “female”, an adjectival form of ᴱQ. qin “woman” (PE16/135).
In drafts for the first version of Quenya Personal Pronouns (QPP1) from the late 1940s, Tolkien had various adjectival forms based on the root ᴹ√(G)ERE/(G)RÉ “bear, produce” such as ᴹQ. rea “female”, réna, or ᴹQ. ríte “female [of any kind]” (PE23/87), but the relevant sections were rejected and there are no signs of the root ᴹ√RÉ in the revised text.
A noun appearing as {rāna >> rāne >>} réna in The Etymologies of the 1930s under the root {ᴹ√RAG >>} ᴹ√REG “edge, border, margin” (Ety/REG; EtyAC/REG). Presumably its meaning is similar to that of the root.
