akimbo:  Akimbo was borrowed from Old Norse. Its original English spelling (which occurs only once, in the Tale of Beryn 1400) was in kenebowe, which suggests a probable Old Norse precursor *i keng boginn (never actually discovered), meaning literally ‘bent in a curve’ (Old Norse bogi is related to English bow); hence the notion of the arms sticking out at the side, elbows bent. When the word next appears in English, in the early 17th century, it has become on kenbow or a kenbo, and by the 18th century akimbo has arrived. => bow
c. 1400, in kenebowe, of unknown origin, perhaps from Middle English phrase in keen bow "at a sharp angle," or from a Scandinavian word akin to Icelandic kengboginn "bow-bent," but this seems not to have been used in this exact sense. Many languages use a teapot metaphor for this, such as French faire le pot a deux anses "to play the pot with two handles."
