There are around 7,000 languages in the world, and if you've studied one you might have had the realization that you could study another…and another...make that ALL the languages. But is it a good idea to study multiple languages at a time, or is it confusing? Does it make it harder to learn them well?

Answer: Thankfully, your brain can definitely handle learning two (or more!) languages at once! (Two down, 6,998 to go.) But there are also some ways you can make this linguistic task easier on yourself.

In this post, we'll share ideas for studying multiple languages at the same time, and we'll look at some research on language learning!

How your brain juggles multiple languages

The human brain is made for learning languages, plural. In some parts of the world, learning multiple languages from birth is the norm, or the language used in schools is different from the language actually used by the community. And sometimes parents themselves speak different languages with their kids, so there is no single "community" language! There are even cultures where everyone is expected to marry someone from a different language group, so language learning is an ordinary part of life.

For languages you already know really well, like your first language, you have strong connections between ideas (what you want to say) and the words you use to express them. So when you learn a new word, in a new language, your brain starts building links from the idea to the new word — but initially the new word is connected to its translation in your own language, instead of to the idea itself. You need lots of practice and input (language you can learn from) to develop strong connections directly from the idea to the new word.


Early in the learning process, you're likely to translate through your first language when thinking of words in your new language (top image). As you get more proficient, you'll build stronger connections directly to the new language (bottom image).

Your brain generally learns and stores all the languages you know in the same regions, so there's always going to be overlapping connections between translations (like cat and Spanish gato), words that sound similar (like vase and Spanish vaso 'cup, glass'), and especially words that sound alike and have shared meanings (like flower and Spanish flor 'flower'). Your brain can't help but activate (remember and call to the surface) these related words. It happens with lifelong bilinguals, too!

So how do multilinguals manage to use just one language at a time? Lots and lots of practice! Learning to suppress one language, and all its connections, is a cognitive skill that lifelong bilinguals are experts in. The early stages of learning multiple languages might be the hardest, but there are lots of ways you can help yourself get used to this kind of practice.

Tips for learning two languages at once

Here are some ways you can make studying multiple languages manageable and productive:

illustration of a wristwatch Double your study time. For most adults, the real challenge of learning multiple languages at once is time. It's really important to get enough input in each language you study. If you were studying German for 30 minutes a day and want to add Spanish to the mix, cutting 30 minutes in half typically means getting less input in each language. You might need to double the total time you study to get the same results in each language!

There will be pros and cons to studying any pair of languages together. If the new language is similar to one you already know or have been studying, you might get a hang of the basics pretty quickly -- but it could be hard to keep two rather similar languages, like Spanish and Italian, apart. On the flip side, studying two unrelated languages, like Spanish and Japanese, might mean less confusion between words and rules, but there might be less you can "transfer" from one to the other.

Consider studying just one language to start, until you have a solid foundation. (In Duolingo courses, that might mean getting through the first three units.) Once you have a good command of basic vocabulary, grammar, and building sentences, then try adding another language. (You can learn unlimited languages on Duolingo for free!)

At the beginning, try studying for longer sessions (like a full 30 minutes of German all at once) instead of breaking it up (like 15 minutes in the morning and 15 more in the evening). This gives you more time to get in "German mode" or "Spanish mode" and really sink into the language. As you get more comfortable and more proficient, you might not need as much time to settle into each language!

Especially at the beginning, try separating your languages by time and location. For example, you could make a habit of always studying German in the morning in the kitchen and studying Spanish after dinner on the couch. This can also help you get in the "mode" of each language! As you get more proficient in the languages, you can try being less rigid about your study contexts.

For example, make flashcards with words in the two languages (like one side German, one side Spanish) and don't use your own language at all! You can color-code the words to help separate them, like always writing German in blue. On Duolingo, you can also try the Spanish course for German speakers, to get extra practice in both languages at once!

Language learning never has to stop 💘

Once you fall in love with one language, you'll be itching to study more! When studying two or more languages at the same time, make sure to spend lots of time with each, to get that all-important language input. There's no limit to how many you can learn with enough practice!
