Language barriers are my least favorite part of traveling abroad. I always try to pick up at least the basics (always recommended) before arriving at my destination but it’s still frustrating to be a tourist at times. Even though English is generally spoken and understood the world over, locals always appreciate an attempt.
If you’re interested in going beyond the basics, take an online language course. There are many sites that offer lessons for free - a quick Google search will reveal a ton of options.
Bonne chance, buena suerte, buona fortuna… good luck!
