queren

noun. pivot, revolving centre, pivot, revolving centre, *axis

A word appearing in its stem form querend- in etymological notes from the mid-1960s, with the glosses “pivot” and “revolving centre” (PE17/65). It was based on the root √KWER “revolve”, and its isolate would reduce to ✱queren.

Neo-Quenya: In a post on 2024-11-08 in the Vinyë Lambengolmor Discord Server (VLDS), Luinyelle suggested this word might also mean “✱axis”.
