hallux (English)

Where does "hallux" come from?

The English noun 'hallux', meaning a big toe, was borrowed from Late Latin 'hallux'[1]. This Late Latin form itself derives from the Latin words 'allus' and 'hallus'[1]. The underlying history of these Latin terms involves related variants like 'allex'[2].
