quilt: [13] The ultimate source of quilt is Latin culcita ‘mattress’, which passed into English via Old French cuilte. Its function gradually evolved from that of a mattress for lying on to that of a coverlet for lying under. A long-standing characteristic of such quilts is that their stuffing is held in place by cross-stitching. This does not emerge as a distinct meaning of the verb quilt (‘sew padded cloth in a crisscross pattern’) until the mid-16th century, but it is reflected in the medieval Latin term culcita puncta ‘pricked mattress’ – that is, a mattress that has been stitched.

This passed into English via Old French as counterpoint, which was subsequently altered, by association with pane ‘panel’, to counterpane [17].
