'customarily-influenced' originates from the combination of 'customarily,' derived from 'custom,' and 'influenced,' from Latin 'influere,' meaning 'to flow into.'

'customarily' evolved from Middle English 'custumary,' and 'influenced' from Old French 'influencer,' eventually forming the modern English term 'customarily-influenced.'

Initially, it meant 'affected by customs,' and this meaning has largely remained the same in modern usage.
