The word "dozen" usually refers to a group of how many objects?

The story behind the answer

A “dozen” means 12. The term comes from Old French “douzaine,” rooted in Latin “duodecim” (twelve). It became a standard counting unit in trade because 12 is highly divisible (by 2, 3, 4, and 6), making it practical for splitting goods evenly.

You see dozens everywhere: eggs are sold by the dozen, clocks show 12 hours, a foot has 12 inches, and there are 12 months and zodiac signs. A fun related term is the “baker’s dozen,” which is 13—historically, bakers added one extra to avoid penalties for selling underweight bread. Memory tip: picture an egg carton—12 spots—whenever you hear “dozen.”
