Aggie

Aggie is an English diminutive form of Agnes, which derives from the Greek name Hagnē, rooted in the word hagnos, meaning pure or chaste. The name Agnes gained widespread use in medieval Europe through the veneration of Saint Agnes, a young Roman martyr of the early fourth century. Aggie has long served as an affectionate short form in both British and American English. Related forms include Aggie's source name Agnes, as well as the Scottish variant Senga.
