Since I have had several multilingual people respond on this blog in the past, here is a little questionnaire (English monolinguals can also answer some of these):
1. Which language(s) that employ either the Latin or Cyrillic script do you think would be the most challenging for an English native speaker to learn and why (I'm excluding most other scripts due to availability and my inability to distinguish letters in Arabic script)?
2. Which language(s) have the richest variety of written works in the three traditional genres (prose, drama, poetry)?
3. If you are aware of it, which language(s) have a healthy or at least growing SF/F scene(s)?
4. If you want to learn any other language besides the one(s) you already know, which one(s) would that be and why?
Very curious to hear your thoughts. I know I'm having to focus a lot more on French and German at the moment, due to having students enrolled in elementary levels at the drug rehab center where I teach and those certainly will receive first priority in the coming months, but I am tempted to learn at least the reading rudiments of at least one other, so comments might sway me a bit here.
