originFrom Middle English ruddocke, ruddok, roddok, from Old English rudduc, ruduc (“robin, ruddock”, literally “little red one, red-ling”), equivalent to rud (“redness”) + -ock (diminutive suffix). The Welsh rhuddog, and Cornish rudhek (“the redbreast”) are probably from the English, although a derivation from a British Celtic *roudākos (< *roudos "red") for all three cannot be ruled out. More at rud.
