Pen

Pen is a Welsh name derived from the Celtic element pen, meaning head or chief, a root that appears widely in Welsh place names and personal names to denote prominence or leadership. As a given name it has been used in Wales both independently and as a short form of longer names such as Penelope or Penlope. The same Celtic root appears in names and words across Brythonic languages, connecting Pen to a broader tradition of pen- compounds in Welsh and Cornish naming conventions.
