Pen

Pen is an English name functioning as a short form of Penelope, which derives from the ancient Greek Pēnelopē, a name of uncertain origin possibly connected to the Greek word for a type of duck or to the weaving thread associated with the legendary wife of Odysseus in Homer's Odyssey. That Homeric heroine, celebrated for her faithfulness and cunning, gave the full name lasting literary prestige throughout Western culture. Pen may also occasionally serve as a diminutive of Penélope, the Spanish and Portuguese cognate. Penny is a related familiar form sharing the same root.
