availability
UK: əˌveɪləˈbɪləti | US: əˌveɪləˈbɪləti
n. the quality of being able to be used or obtained
n. the state of being free or ready to do something
The word "availability" combines "available," derived from Old French a- (to) + vail (worth), meaning "capable of being used or obtained," with the noun-forming suffix "-ity," indicating a state or condition. The root "vail" traces back to Latin valere (to be strong or worthy), reflecting the idea of something being accessible or at one's disposal. Over time, "availability" evolved to emphasize both physical accessibility and readiness for use or interaction.
