hueso NOUN bone; stone
Like so many words in English and Spanish hueso has two different but conceptually related meanings. It can refer to the bones of a person or animal, or to the stones of fruit and olives.
un corte de carne con hueso a cut of meat on the bone
aceitunas sin hueso pitted olives
When you get soaked in a downpour, you are calado hasta los huesos soaked to the skin, literally soaked to the bones.
Remember that hueso does not refer to fish bones. The word for these is espinas:
Con las espinas puedes hacer fondos de pescado. With the bones you can make a fish stock.
