O'r fwyalchen ddu bigfelen, You fly so swiftly, you climb so high. Ei di dros oi at y ddynes For I've not the gift nor the wings to fly Tell her now that my heart is breaking, Tell her to this earth I'm bound, For she gave me no true answer, And now I have lost all the love I found O'r fwyalchen ddu bigfelen The sun on the mountain, the wind at sea. Mae fy nghalon i cyn drymed And none but the morning mist weeps for me Tell her now that my heart is breaking, Tell her to this earth I'm bound, For she gave me no true answer, And now she lies in the cold, dark ground Tell her now that my heart is breaking Can an swynol iddi hi, For she gave me no true answer, A nawr mae nghwsg yn y ddaer ddu./
