The condition of being more desirable or favorable than something else.
The preferability of this option makes it the best choice for our project.
Preferability → It is formed from "pre-" (meaning before) and "ferre" (meaning to carry or bring) combined with the suffix "-ability" (meaning the quality of being). The word "preferability" refers to the quality of being preferred or the state of being more desirable than something else.
Think of something that is 'brought before' ('pre-') as being more desirable or better — that's what preferability means.
