Aggie

Aggie is an English pet form of Agnes, which derives from the ancient Greek name Hagnē, rooted in the adjective hagnos meaning pure or chaste. The name became widely used in medieval Europe through the veneration of Saint Agnes of Rome, a early Christian martyr whose feast day is celebrated on January 21. Aggie has long served as an informal everyday diminutive, particularly in Scotland and Ireland, where Agnes remained common for centuries. Related forms include Agness, Nessa, and Ines.
