scallion
Scallion (noun) means a slender green onion with a mild flavour, also called a spring onion, from the species Allium fistulosum.
Etymology
Comes from Middle English scaloun (“shallot”), from Anglo-Norman scalun (a variant of Old French eschaloigne), from a Proto-Romance derivation of Vulgar Latin *escalonia, from Latin Ascalonius (as in caepa (“onion”) Ascalonius, "shallot"), from Ascalo (“Ascalon”), from Ancient Greek Ἀσκάλων (Askálōn, “Ascalon, an ancient port city in the Levant”), which was borrowed from Biblical Hebrew אַשְׁקְלוֹן (ʾašqəlôn).
