When fat it is prized by epicures. Called also dunne. The name is said to be derived from King Canute, this bird being a favorite article of food with him. "The knot that called was Canutus' bird of old, Of that great king of Danes his name that still doth hold, His appetite to please that far and near was sought." (Drayton) Origin: OE. Knot, knotte, AS. Cnotta; akin to D. Knot, OHG. Chnodo, chnoto, G. Knoten, Icel. Kntr, Sw. Knut, Dan. Knude, and perh. To L. Nodus. Cf. Knout, Knit. Source: Websters Dictionary (01 Mar 1998) |
