chest: [OE] Chest comes ultimately from Greek kístē ‘box, basket’. In Latin this became cista (source of English cistern [13]). In prehistoric times the word was borrowed into Germanic as *kistā, which was the source of Old English cest. This still meant ‘box’, a sense which continued in isolation until the 16th century, when it was first applied to the ‘thorax’ – the basis of the metaphor presumably being that the ribs enclose the heart and lungs like a box. It has since replaced breast as the main term for the concept.
