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

'customarily' evolved from the Middle English word 'custumary,' and 'linked' from the Old English word 'hlincan,' eventually forming the modern English term 'customarily-linked.'

Initially, 'customarily' meant 'according to custom,' and 'linked' meant 'connected.' Over time, the combined term 'customarily-linked' evolved to mean 'typically associated with.'
