Refloat → It is formed from "re-" (meaning again) and "float" (from Old English "flōtan", meaning to float or to be buoyant). The word "refloat" means to cause something to float again after it has sunk or become submerged.
Think of making something float 'again' — 're-' means again, and 'float' refers to being buoyant.
