means A white, nutrient-rich liquid produced by the mammary glands of mammals to feed their young, and consumed by humans (often from cows) as a drink and the base for dairy products.

from From Old English 'meoluc' or 'milc,' tracing back through Proto-Germanic 'meluks' to a Proto-Indo-European root '*h₂melǵ-' meaning 'to wipe' or 'to stroke' — the very gesture of the hand drawing milk from a teat. The same root reaches across to Latin 'mulgere' and Greek 'amelgein,' both meaning 'to milk,' so half of Europe named the liquid after the motion of getting it.
