[Caballero]

While it might not be considered the same language, it is awfully close (see my message above), especially in written form (I can read it just fine and I've never studied it.) So, the more Spanish you understand, the more Valencian you will be able to understand, especially if you ask the person to write it down. Many people think it looks like a cross between French and Spanish, or the halfway point between the two languages.
