Etymology

Origin of udder

before 1000; Middle English uddre, Old English ūder; cognate with German Euter, Latin ūber, Greek oûthar, Sanskrit ū́dhar

Explanation

A cow's udder is the part of its body that produces milk. When you milk a cow, you empty its udder by squeezing the milk into a bucket. Moo! To milk any four-legged ruminant, you need to carefully squeeze and pull each teat after cleaning the udder. Large dairy farmers use machines to do this, while some smaller ones do it by hand. Female cattle, goats, deer, and sheep all produce milk and have udders, organs in their bodies that contain mammary glands.
