Morphology

buoyancy = buoyant (transparent) = buoy + ant + ancy

Formed from the adjective 'buoyant' with a standard noun-forming suffix to denote the quality or state of being buoyant (ability to float).

Etymology

Buoyancy comes from buoy, a floating object used at sea, and that word comes from an old Dutch word meaning 'to float'. So, buoyancy is the power or ability to 'float' in water, air, or another fluid.
