'adjustor' originates from the Latin word 'adjuxtare,' where 'ad-' meant 'toward' and 'juxtare' meant 'to bring together.'

'adjuxtare' transformed into the Old French word 'ajuster,' and eventually became the modern English word 'adjustor' through Middle English.

Initially, it meant 'to bring things together,' but over time it evolved into its current meaning of 'a person who adjusts or assesses.'
