'customarily-made' originates from the English word 'customary,' which comes from the Latin word 'consuetudinarius,' where 'consuetudo' meant 'custom or habit.'

'customarily' evolved from the Middle English word 'custumary,' which was derived from the Old French 'costumier,' and eventually became the modern English word 'customarily.'

Initially, it meant 'according to custom or tradition,' and this meaning has largely remained the same in modern usage.
