Allie is a shortened form of Alice, an English name derived from the medieval feminine given name Alice, which has been widely used throughout Europe since the Middle Ages. The name Alice is thought to come from the Germanic word "adali" meaning "noble," or from the Old French name Aalis, meaning "truthful." Allie, while seeming modern, actually has historical precedent dating back to the 17th century and remains a popular choice for parents today due to its simplicity, familiarity, and timeless associations with nobility and virtue.
