What does preferability mean?
Preferability means the quality of being preferable: the condition that makes one person, thing, or option more desirable than another. It is especially useful when discussing a comparative advantage, even if that advantage is limited or difficult to measure. For example, a faster service may have greater preferability, although its benefits might come at the cost of higher prices or reduced reliability. The word can apply to choices, products, methods, arrangements, and abstract ideas. It is more formal and less common than preference, which can refer either to the act of choosing something or to the fact that someone likes one option better. Preferability is also narrower than advantage because it focuses on being chosen or regarded as better. In ordinary conversation, speakers are more likely to say preferable, preferred, better, or more desirable.

Where does preferability come from?
Preferability was formed in English by combining prefer with the suffix -ability, meaning the quality or state of being able to be preferred. The related adjective preferable and noun preference belong to the same word family. The verb prefer comes through Old French from Latin praeferre, a compound of prae-, meaning before, and ferre, meaning to bring or carry, with its original sense related to placing something before another.
