'suitably-distributed' originates from the combination of 'suitably' and 'distributed'. 'Suitably' comes from 'suit', which originates from Old French 'suite', meaning 'attendance', and 'distributed' comes from Latin 'distribuere', where 'dis-' meant 'apart' and 'tribuere' meant 'to assign'.

'Suitably' evolved from the Old French 'suite' to the modern English 'suit', and 'distributed' evolved from the Latin 'distribuere' to the modern English 'distribute'.

Initially, 'suitably' meant 'in a manner that suits', and 'distributed' meant 'to divide among', which has largely remained the same in modern usage.
