We take a look at the Foreign Service Institute language difficulty rankings used to determine how hard a language is to learn

Foreign Service Institute language difficulty rankings indicate the time it would take a native English speaker to achieve proficiency in various languages.

There are five categories, ranked from easiest to hardest based on the number of classroom hours a learner would need to achieve professional working proficiency (i.e., Level 3 on the Interagency Language Roundtable scale).
