fem. proper name, from French Dorothée, from Latin Dorothea, from Greek, literally "gift of God," from dōron "gift" (from PIE root *do- "to give") + fem. of theos "god" (from PIE root *dhes-, forming words for religious concepts). With the elements reversed, it becomes Theodora. The accessory called a Dorothy bag is so called from 1907.
