I don't speak any Spanish. Does 'de' always mean 'of'? Does 'a' always mean 'to'? I'd find it unlikely. Are there rules for when talking about countries?
FWIW the Giro d'italia has similar 'issues'. Where giro/girare means many different things like journey, tour, turn, rotate and many more depending on what you put on it. What has this got to do with Spanish? Vuelta appears to my untrained eye to come up with very similar dictionary listings as those that giro/girare does. In italian (mine is bad) I have a book with a list of verbs and propositions and there are as you'd imagine some differences between English/Italian i.e some where English uses the preposition and Italian doesn't and vice versa or a different one is used instead. I'd imagine it's like that in spanish, but don't know the specifics.
