shank: [OE] Shank originally meant ‘leg’, or more specifically ‘shin’ (Edward I of England was nicknamed ‘Longshanks’ on account of his long legs). The word goes back to a prehistoric West Germanic *skangkan, which also produced Dutch schenk ‘leg-bone’ and is closely related to German schinken ‘ham’. Its ultimate origins are not known, although it has been suggested that it arose from the notion of ‘crookedness’ or ‘lameness’ (in which case German hinken ‘limp’ may be related). The main modern meaning of shank, ‘stem, shaft’, emerged in the 16th century. [shank etymology, shank origin, 英语词源]
