Where did expression stuck in your craw come from?

The expression "stuck in your craw" originates from the anatomy of birds, where the "craw" refers to the crop or pouch that holds food before it is digested. When something is "stuck in your craw," it implies that an idea or feeling is difficult to digest or accept, much like indigestible food in a bird's crop. The phrase has been used since at least the 16th century, often to describe feelings of irritation or resentment about a situation.
