The map above visualizes the languages of Europe (at least those deemed diplomatically important enough to be taught at the FSI), coloring them according the average time commitment they require of an English speaker. In pink, we have the English-speaking countries. The red countries speak Category I languages, those most closely related to English and thus learnable in 575 to 600 hours of study: the traditional high-school foreign languages of Spanish and French, for instance, or the less commonly taught but just about as easily learnable Portuguese and Italian. If you’d like a little more challenge, why not try your hand at German, whose 750 hours of study puts it in Category II — quite literally, a category of its own?
