'adjustment' originates from the Old French word 'ajustement', where 'a-' meant 'to' and 'juster' meant 'to bring near'.

'ajustement' transformed into the Middle English word 'ajustement', and eventually became the modern English word 'adjustment'.

Initially, it meant 'to bring something into proper position', but over time it evolved into its current meaning of 'the act of making something more suitable'.
