"Reloj" originally comes from latin "horologium".


I've read that the "j" ending is a result from catalan "relotge".

I can think of another word ending in "j", "carcaj" which means "quiver" as the container used to carry arrows. Apparently this comes from French "carcais".


In this website they list some words ending in "j" although I would say only "reloj" and "carcaj" are actually used.

From that list, Boj is also quite known, at least in Spain because there is a quite famous novel called "Madera de boj" written by the very well-known writer "Camilo José Cela". I agree the rest are unused (at least I have never seen or heard of any.) – Javi Apr 19 '12 at 7:19
I agree. Reloj, boj and carcaj are the only ones I've ever heard from that list. – MikMik Apr 19 '12 at 8:48
Esto es tramposo, ya o sé, pero habría que agregar estas dos palabras son muy usadas: contrarreloj y puaj. – Rodrigo Mar 25 '15 at 11:58
