Possibly from Welsh cyrrid "bent" or cerdd "poetry" combined with ven "woman" or gwen "white, fair, blessed". According to medieval Welsh legend this was the name of a sorceress or goddess who created a potion that would grant wisdom to her son Morfan. The potion was instead consumed by her servant Gwion Bach, who was subsequently reborn as the renowned bard Taliesin.
