Etymology
< NLem koxl‑a ‘unit of velocity’, academic loan of
< Koi κόχλ‑ος ‘snail (shell)’, probably related to
Koi κόγχ‑η ‘mussel’
< SHell *kónkh‑ā
< PIE *kóngʰ‑eh₂ ‘shell, mussel’
The name of the basic speed unit was chosen for its slowness. It was redefined from a unit of speed to one of rapidity upon the discovery of Lorentz symmetry.
