TRIVIAL PURSUITS: Why Does lb Stand for Pound?

August 10, 2010 (PLANSPONSOR.com) - The word "pound" is abbreviated "lb”, letters that appear nowhere in the word for which they serve as an abbreviation.

What does lb “really” stand for?

Answer:

The Latin words “libra pondo” describe a Roman unit of weight similar to a pound, and the abbreviation “lb” for a unit of weight is derived from the Latin word libra. 

The word “pound” itself comes from the Latin pendere, to weigh, while libra meant “scales and balances”.
