'inform' originates from Latin, specifically the word 'informare,' where 'in-' meant 'into' and 'formare' meant 'to form or shape.'

'informare' transformed into the Old French word 'enformer,' and eventually became the modern English word 'inform' through Middle English.

Initially, it meant 'to shape or form,' but over time it evolved into its current meaning of 'to give information.'
