A word used in its plural form kelvar to describe animals in The Silmarillion, as opposed to Q. olvar = “plants” (S/45). In a marginal note to a short document on Ents and Eagles from 1958-9 (or later), it was translated “animals, all living things that move” (WJ/341); this document was the basis for the reference in the published version of The Silmarillion. The word kelvar was also translated as “animals” in some notes the Death of Animals and Plants from 1957-8 (NM/271), where it was a replacement for deleted Q. kuivar along with a note explaining the reason for the change being that “cuy = awake not live” (NM/274 note #6).

Possible Etymologies: Wynne, Smith, and Hostetter suggested kelvar might be derived from 1930s ᴹ√KEL “go, run (especially of water), flow away downhill” from The Etymologies (VT43/31), perhaps in the sense of “a thing that runs”. If this is the case, kelva would be the only derivative of that root not connected to flowing water.
