'advisability' originates from the word 'advisable', which comes from the Latin word 'advisare', where 'ad-' meant 'toward' and 'visare' meant 'to look at'.

'advisare' transformed into the Old French word 'aviser', and eventually became the modern English word 'advise', from which 'advisability' is derived.

Initially, it meant 'to look at or consider', but over time it evolved into its current meaning of 'the quality of being advisable'.
