5, finger, fist, ?fight

>> I just read (Science 303:1322, 27.2.04) that the words "five", "fist" and

"finger" have a common origin. Where can I find more about this? Are these
words related to the word "fight"? Thanks for any help.

> One explanation of English fist, Geman Faust, OCS pestI "fist" is: IE

*pNkwsth2i- from *penkwe- "five" and *stah2- "stand", ie. "five (fingers)
stand together".

Nice explanation. Thanks a lot, Simona. Do you happen to know where I can
find more about this?
