Plural of 'gullet': the tube in your throat that food travels down, or grooves and channels in stone or metal.
From Old French 'goulet' (diminutive of 'goule,' meaning throat), which comes from Latin 'gula' (throat or gullet). The word traveled from Latin through French into English.
The same word describes both your body and architectural decorations because medieval people thought poetically about anatomy—a groove in stone reminded them of a throat!
