Gareth is the name of one of the Knights of the Round Table in the Arthurian legends, the son of Lot and Morgause, Arthur’s older half-sister, which makes him Arthur’s nephew. The name first appeared in Thomas Malory’s Le Morte d’Arthur, based on the name Gahariet, an Old French form of the name. The etymology behind the name is uncertain though it has been linked to Welsh gwaredd meaning “gentleness”. It could also be connected to another name, Geraint, the Welsh form of Latin Gerontius meaning “old man” from Greek geron. Other possible meanings I’ve come across is that it might be from Welsh Gweir “grass”, “hay”, “collar”, “loop” or “bend” or Gweirydd “Gweir + lord”, or that it could be from Old Welsh gwrhyt “valor”.
