early 13c., from O.Fr. changier "to change, alter," from L.L. cambiare "to barter, exchange," from L. cambire "to exchange, barter," of Celtic origin, from PIE root *kamb- "to bend, crook" (with a sense evolution perhaps from "to turn" to "to change," to "to barter"). Related: Changed; changing.
Удивительное латинское слово «cambire». Не увидеть здесь слова «забирать», при переходе «з» - «с» - это надо уметь.
