'scallion' originates from Middle English, specifically the word 'scaloun', which came from Old French 'escalogne', derived from Latin 'Ascalonia (caepa)', meaning 'onion from Ascalon'.

'scaloun' transformed into the modern English word 'scallion'.

Initially, it referred to onions from Ascalon, but now it generally refers to young onions with long green stalks.
