Oh…oh, I get it. Learn Latin.

Learning a European language, especially from a country that had colonised other countries will be useful. French and English, for the most part. Learning a romance language will also help if you were to touch Latin someday

I’d learn Mandarin next since there’s a lot of speakers and Asia is a fun place. Japanese after that if I have the time. That would be my personal journey if I ever learn any other languages, but we’ll see

I say French, it’s a much more commonly spoken language than most people in the US realize, if you look at your food or chemical labels, you often see it’s the second used language followed by spanish

The ones that interest you the most will be easiest to stick with. I find things just through my general interests and poking around.

Favorite music genre? Listen to bands from different countries and see how they sound. TV shows, movies, and documentaries from other countries are another big one. Listen to the original language, see if it sounds interesting, maybe read a little about it.

Or maybe you know someone who you’d like to be able to talk with in their language. It could be anything. Pick one or two things to try and you’ll get a feel for what you like.

Klingon!

I’ve been learning Norwegian Bokmål and it’s pretty interesting seeing all the words that it and English have in common (as well as their differences).

Also, Toki Pona as others have mentioned. Might seem like a joke language at first, but the community is really vibrant and kind. You can make some real, meaningful connections through it. Plus, it takes maybe a weekend to get good at Toki Pona.

Latin is very interesting, gives you the ability to read the original untranslated works of famous Roman historical figures and also helps you with nomenclature in science ( like for biology, medicine, etc)

I just watched this video on toki pona. Really interesting in how it’s easy to learn but the difficulty comes from trying to communicate complex ideas.
