Etymology

Origin of beak

1175–1225; Middle English bec < Old French < Latin beccus < Gaulish

Explanation

When you see a bird pecking around in your backyard, it’s using its beak to probe the ground for food. A beak is the hard, pointed structure sticking out from a bird’s face. The word beak refers to the bill on a bird, which protrudes from the face and is used for eating, grooming, and pecking. You can think of it sort of like the mouth of a bird, only it’s made up of hard, horny material rather than flesh. The word beak is sometimes used informally to refer to a person’s nose, especially if the nose is large, prominent, and protruding — in other word, sort of like a bird’s beak.
