A word for “crooked” derived from √RIK “twist” appearing in notes associated with the Quendi and Eldar essay of 1959-60 (VT39/7, 9). ᴹQ. raika also appeared in The Etymologies of the 1930s with the glosses “crooked, bent, wrong” under the root ᴹ√RAYAK (Ety/RÁYAK). It appeared in its (1930s-style) plural form raikar in various versions of the Lament of Atalante from the 1930s and 40s in the phrase ilya sí maller raikar “now all roads (are) bent” (LR/47; LR/56; SD/310).
Note that The Etymologies of the 1930s also had ᴹQ. téra “straight, right” (Ety/TEƷ). So it seems Quenya used the metaphor “straight = right” and “crooked = wrong” (at least in the 1930s).
Conceptual Development: The Qenya Lexicon of the 1910s had similar forms ᴱQ. pere̜qa “crooked” and ᴱQ. perqa “wrong” (QL/73).
