Uncoil → It is formed from "un-" (meaning not or opposite of) and "coil" (from Old French *coiler*, meaning to wind or twist). The word "uncoil" means to reverse the action of coiling, or to straighten something that has been wound up.
Think of 'un-' meaning to reverse and 'coil' meaning to wind — so uncoil means to unwind something that has been twisted.
