As Lore said, the generic name used in Spanish to refer not only sausages but other similar products is "embutido". Yeah, as James said, perhaps it does not make sense but it's the convention. In Mexico, for example, all supermarkets have an "embutidos" department where you can get all kind of "salchichas", "chorizos", "salchichón", etc. You'll never find a "salchichas" department. Did I made my point? Kind regards!

Yes, the generic name is "embutido" and sausages are "salchichas"

Look, salchicha is the tradicional, is thin, the salchichon is prepared with different meats than sausage and thicker in proportion

> Yes, the generic name is "embutido" and sausages are "salchichas" That doesn't make sense.

"Salchichón" is a kind of sausage which is similar to salami (i.e. dried cured/spiced sausage), whereas "salchicha" is the general term for a sausage.
