calabozo

dungeon; prison, jail; prison cell

“Al día siguiente, el 5 de mayo, la tía fue a buscar a su sobrino al calabozo y le informaron que había fallecido.” — The next day, May 5th, the aunt went to the jail in search of her nephew and was informed that he had died.

Uncertain. Perhaps from Late Latin *calafodium, based on Latin fodiō (“to dig, bury”).
