'infer' originates from Latin, specifically the word 'inferre,' where 'in-' meant 'into' and 'ferre' meant 'to carry.'

'inferre' transformed into the French word 'inférer,' and eventually became the modern English word 'infer' through Middle English.

Initially, it meant 'to bring in or carry in,' but over time it evolved into its current meaning of 'to deduce or conclude.'
