Any time anyone asks what superpower I would mostly like to have, I always answer that I would like to speak every language with native fluency. And yet, I've rarely if ever done anything to approach that goal. Daniel and I did take a semester of French at SMU one time. That was fun but without continued effort didn't really stick.
Then my best seven foot tall woman friend suggested I download DuoLingo. It's free and you can learn any number of languages. So I did, and I started taking French lessons. Then I decided to throw in German since I already know it pretty well and it would be fun and easy to refresh. Then we planned a trip to Portugal so I focused on learning was Portuguese I could in the months leading up to our departure.
THEN I got so sick of the advertisements that I paid for a subscription. They got me. I admit it. But now that I'm paying for it, I'm going all in. I am currently switching daily between: French, Germany, Portuguese, Spanish, Italian, Japanese, and Danish. What's weird is that while switching between them certainly slows my progress, learning seven sets of vocabulary at once hasn't really proven to be any more difficult than one.
I know that these little exercises and AI driven conversation and voice recognition are unlikely to make me fluent. They're unlikely to allow me to converse easily in a foreign country. But I don't really care. Because (A) it's fun, (B) it's better than doom scrolling, and (C) it really does teach you a LOT if not all you need to know. When we were in Portugal, I busted out a few phrases with your guides (which of course ended with hilarious failure as I spoke Brazilian Portuguese), but also just consumed words around me. I knew what the little Brazilian kid was talking about when he screamed, "Abacaxi! Aacaxi!" at the top of his lungs (he saw a pineapple laying on the ground).
And that was enough for me. I cannot explain how utterly maddening it is for me in a foreign country to see words all around me and not know what they mean. I don't CARE what they mean. It just bothers me not to know. This really helped with that mental fatigue. To see a sign in a store window and know that it says "Closed on Mondays." It allows me to move on and not fixate on wanting to stop and translate.
So anyway, that's my plug for DuoLingo. It's free if you can withstand the most obnoxious assault of ads for phone games deliberately designed to wear you down into signing up for a subscription. But if you've ever been even a little curious, this is a super low effort, low risk way to delve into it and feel like you're accomplishing something every day.
