Morphology

buoyant = buoy (transparent) = buoy + ant

The adjective is directly formed from 'buoy' with the adjectival suffix '-ant', producing the literal meaning 'able to float'.

Etymology

Buoyant comes from the same idea as the word buoy, a floating marker, and from old French words meaning 'to float'. So to be buoyant is to be able to 'float' or rise easily in water or air.
