Joe and I have traveled to several countries where English was not the native tongue. Joe took Latin in school so his ability to translate is limited, but I took Spanish for 8 years, which helped when we went to Cuba in 2016, and immersed myself in Japanese In 10 Minutes A Day back in the mid-90s, which helped quite a bit the very first time I visited there.
Over the years we’ve noticed less and less need to learn much of other languages when traveling. If you have internet access, there are plenty of ways to get translation on the fly, and even without data access, there are offline apps, plus miming can go a long way, or you can even wear clothing that will help with the basic of basics.
That being said, it still helps immensely to have a little bit of knowledge under your belt of the language of the country you’re going to visit, even if it’s just a limited yes, no, thank-you, you’re welcome, I’m sorry, the numbers 1-100 and the “question” words of who, what, why, where, when and how. Obviously, for such limited words or phrases, you may not want to spend a fortune. Fortunately, there’s an online series of courses that can teach you close to 40 languages, and they’re FREE! And besides the typical Spanish, German, etc., you know what else they teach?
Klingon and High Valyriand.
I see your eyes lighting you, travel friends who are nerds on the side ;-)/
