Etymology of caliber
Posted by Johannes on 16 November 2010
Caliber comes from the old French calibre (14c.), from the Arabic qalib “a mold, last”, which derives from the Greek calapous [Gr: καλάπους] “a shoemaker’s last” lit. “little wooden foot,” from calon “wood” + pous “foot”.
From the same root: calibrate, calibration.
In modern Greek (Romeika):
a) calapodi: a shoemaker’s last, a little wooden foot [Gr: καλαπόδι]
b) calibraro: calibrate [Gr:καλιμπράρω], loanword
