Calliper
/ˈkælɪpə(r)//ˈkælɪpər/The word "caliper" originates from the Old French word "calibre," which means "diameter" or "gauge." This, in turn, comes from the Latin word "calaber," meaning "of a large size." Early calipers were likely simple tools used to measure the diameter of objects like barrels, hence the connection to size. Over time, the word evolved to encompass more complex measuring devices, including the calipers we know today. The modern "caliper" spelling likely emerged due to the influence of the Latin word "calix," meaning "cup," which was used to describe some types of calipers.
