'suitably-assigned' originates from the combination of 'suitably' and 'assigned', where 'suitably' comes from 'suitable', meaning 'appropriate', and 'assigned' from 'assign', meaning 'to allocate'.

'suitably' evolved from the Old French word 'suitable', and 'assign' from the Latin word 'assignare', eventually forming the modern English term 'suitably-assigned'.

Initially, it meant 'appropriately allocated', and this meaning has largely remained the same in modern usage.
