'proportioned' originates from Latin, specifically the word 'proportio', where 'pro-' meant 'for' and 'portio' meant 'part or share'.

'proportio' transformed into the Old French word 'proportioner', and eventually became the modern English word 'proportion' through Middle English.

Initially, it meant 'to divide into parts', but over time it evolved into its current meaning of 'having a balanced or harmonious arrangement'.
