kiln: [OE] Etymologically a kiln is for ‘cooking’, not for burning or drying. Its distant ancestor was Latin coquīna ‘kitchen’, a derivative of the verb coquere ‘cook’. This produced an unexplained variant culīna (source of English culinary [17]), which was used not only for ‘kitchen’, but also for ‘cooking-stove’. Old English adopted it as cylene, which has become modern English kiln. => cook, culinary, kitchen[kiln etymology, kiln origin, 英语词源]
