cot (n.1)

"small, light bed," 1630s, from Hindi khat "couch, hammock," from Sanskrit khatva, probably from a Dravidian source (compare Tamil kattil "bedstead"). Sense extended to "canvas hammock bed on shipboard" (by 1769), then "portable bed of canvas or similar material, fastened to a light frame, capable of folding up" (1854). Meaning "small bed or crib for a child" is by 1818.
