Etymology

Origin of limb1

First recorded before 900; Middle English lim, lim(m)e, Old English lim; akin to Old Norse lim “small branches, foliage,” limr “limb, joint (of meat),” līmi “broom (of twigs), rod,” Latin līmus “askew, aslant,” līmen “transverse beam, threshold, lintel”; the spelling limb first appears at the end of the 16th century, probably influenced by limb 2 ( def. )

Origin of limb2

First recorded in 1350–1400; Middle English limbe, from Old French limbe, and Latin limbus limbus 2; see also limbo 1 ( def. )

Explanation

Willing to pay an arm and a leg for those World Series tickets? Then you're willing to give up two of your limbs for the season's biggest baseball games. Arms, legs, wings, flippers — these are all examples of limbs. But we shouldn't leave out the trees. They've got plenty of large branches or limbs as well. In fact, when you expose yourself to potentially negative consequences in order to help someone else, it's called "going out on a limb" — like crawling out on a big tree branch. Not a flipper.
