French is an extremely useful language seeing as how it is spoken in 34 separate countries around the world, including France, Canada, Belgium, Switzerland and Monaco; to name a few. The Foreign Service Institute (FSI) has categorized all languages into separate categories (I-V) on level of difficulty and how many hours it usually takes to become Speaking 3: ‘General Professional Proficiency in Speaking (S3)’ and ‘Reading 3: General Professional Proficiency in Reading (R3)’. French sits nicely in category 1 where it is indicated that you only need around 23-24 weeks (around 575-600 hours) of study to reach this level. This is quite doable.

There are many different dialects of Arabic which all derive from 3 types of Arabic: Classical Arabic, Modern Arabic and Colloquial Arabic (‘Ammiyya). The issue with Arabic is that it is a very difficult language to learn. If you were to look at Arabic writing at first glance, it may look like a load of squiggles all joined together. It is a very detailed and beautiful written (and spoken) language that ranks in category V in FSI’s difficulty scale.
