noun
udder
UH-der/ˈʌdər/
A milk-producing organ with teats in cows and similar animals.
The cow's udder hangs naturally between the hind legs with four teats.

Etymology
Old English udder already named the animal’s milk glands, especially when large and baggy with more than one teat. The modern meaning preserves that concrete anatomical sense.
In context
Next, we see that the udder is composed of four separate glands, commonly referred to as quarters. The front quarters account for approximately 40% of the total milk production
