From Middle English caudroun, borrowed from Old Northern French caudron, ultimately from Late Latin caldāria (“cooking-pot”), from Latin caldus (“hot”). Spelling later Latinized by having an l inserted. See chowder, caldera. The military sense is a semantic loan from German Kessel; compare English kettling.
