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

'advisare' transformed into the Old French word 'aviser,' and eventually became the modern English word 'advise' through Middle English.

Initially, it meant 'to see or look at something,' but over time it evolved into its current meaning of 'to recommend or suggest.'
