Aggie

Aggie is an English pet form and diminutive of Agnes, which derives from the Greek name Hagnē, rooted in the word hagnos, meaning pure or chaste. The name gained widespread use in the English-speaking world as an affectionate short form, particularly during the nineteenth century when Agnes was a common given name. It is also occasionally used as a nickname for Agatha, from the Greek agathē, meaning good. Agnes, Agatha, and Ag are closely related forms sharing this diminutive tradition.
