the.com/limb
the original Swiss Army tool, evolved from fins that crawled out of the sea
means An arm or leg of a person or animal, or a large branch of a tree.
from From Old English 'lim,' meaning a limb or branch, with deep roots in Proto-Germanic (compare Old Norse 'limr'). The 'b' is a later spelling intruder — it crept onto the end of the word much like the silent 'b' in 'thumb' and 'numb,' though it was never sounded in speech.
