travail

Etymologists are pretty certain that travail comes from trepalium, the Late Latin name of an instrument of torture. We don't know exactly what a trepalium looked like, but the word's history gives us an idea. Trepalium is derived from the Latin tripalis, which means "having three stakes" (from tri-, meaning "three," and palus, meaning "stake"). From trepalium sprang the Anglo-French verb travailler, which originally meant "to torment" but eventually acquired the milder senses "to trouble" and "to journey." The Anglo-French noun travail was borrowed into English in the 13th century, followed about a century later by travel, another descendant of travailler.
