also wish-bone, 1860, from wish (n.) + bone (n.); so called from the custom of making a wish while pulling the bone in two with another person. The wishbone breaking custom dates to the early 17c., when the bone was a merrythought.
early 14c., "act of wishing," also "what one wishes for," from wish (v.). Cognate with Old Norse osk, Middle Dutch wonsc, Dutch wens, Old High German wunsc, German Wunsch "a wish." Wish fulfillment (1901) translates German wunscherfüllung (Freud, "Die Traumdeutung," 1900).
Middle English bon, from Old English ban "bone, tusk, hard animal tissue forming the substance of the skeleton; one of the parts which make up the skeleton," from Proto-Germanic *bainan (source also of Old Frisian and Old Saxon ben, Old Norse bein, Danish ben, German Bein). Absent in Gothic, with no cognates outside Germanic (the common PIE root is *ost-); the Norse, Dutch, and German cognates also mean "shank of the leg," and this is the main meaning in Modern German, but English seems never to have had this sense.
To work (one's) fingers to the bone is from 1809. To have a bone to pick (1560s) is an image of a dog struggling to crack or gnaw a bone (to pick a bone "strip a bone by picking or gnawing" is attested from late 15c.); to be a bone of contention (1560s) is of two dogs fighting over a bone; the images seem to have become somewhat merged. Also compare bones.
Bone-china, which is mixed with bone-dust, is so called by 1854. Bone-shaker (1874) was an old name for the early type of bicycle, before rubber tires.
"wishbone of a fowl's breast," c. 1600, from merry (adj.) + thought. So called from the sport of breaking it between two persons pulling each on an end to determine who will get a wish he made for the occasion (the winner getting the longer fragment). Also see wishbone.
