'advisory' 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 look toward or consider,' but over time it evolved into its current meaning of 'to offer guidance or recommendations.'
