In Spain there are different languages. It's much more exact to say "Castilian or Spanish" than "Spain". In catalan, for example, 'to have lunch' is 'dinar'. In Spain there are, ar least, 7.5 millions people who speak catalan.
Currently there is no English-Catalan dictionary. It is in the pipeline : WR volunteer dictionaries, If you are interested. However since Catalan is a language in its own right, it would be confusing to add it to the English Spanish dictionary.
