Say goodbye to bonjour and hello to headaches.

If you think picking up a little French or Spanish is difficult, then we’ve got some bad news for you: You probably shouldn’t try to learn Hungarian. Or Navajo. Or Thai, which contains an alphabet comprised of a staggering 44 consonants and 32 different vowels. That’s right: Here we’ve compiled the hardest languages to learn on planet earth. And if this list inspires you to take one of them on, be sure you know The Secret Trick for Learning a New Language Quickly.

Finnish difficult languages to learn

1
Finnish

Finnish has a reputation for being a tricky language to learn, and with good reason. Nouns have 15 different cases, while English has only three: subjective, objective, possessive. The language is in the Finno-Urgic language family, so it doesn’t have any Latin or German influence to help you guess what something means.

The one thing that does make it a little easier is that it is written the way it sounds in the same alphabet as English. In theory, pronunciation is also fairly straightforward, but it can be easy to get hung up on long vowel and consonant sounds. And if you find yourself intrigued by a place with such a challenging language, Here’s Why Finland Is the New Happiest Country on Earth.

Russian difficult languages to learn

2
Russian

Russian is rated a four out of five in difficulty by the Foreign Service Institute, so it’s not as challenging as most of the languages on this list. However, there are some definite roadblocks to becoming fluent in Russian, among them being that spelling isn’t always straightforward, it’s full of vowel sounds unfamiliar to the average English speaker, and it requires learning an entirely new alphabet to master.

Vietnamese difficult languages to learn

3
Vietnamese

Unusual grammar, difficult pronunciation, and six different tones make Vietnamese a challenge for English speakers. So, how long does it take to master Vietnamese?

Expect to spend around 1,100 hours in class to attain speaking and reading proficiency, according to the Foreign Service Institute. Still, learning the language is not without merits: Learning Vietnamese can definitely help you navigate around one of the 20 Most Zen Places on Earth.

Mongolian difficult languages to learn

4
Mongolian

The trickiest part of Mongolian is the pronunciation. Once you’ve got that down, the grammar’s not so hard, as long as you know Finnish, and the alphabet’s a breeze, assuming you can read Russian. If you don’t meet those two criteria, though, it is a very challenging language to master.

Hungarian difficult languages to learn

5
Hungarian

Hungarian is a member of the same small language family as Finnish, so the average English speaker won’t be finding much familiarity in its vocabulary. It also has 18 cases and 14 vowels, which makes saying things right particularly difficult.

The language also relies more heavily on idioms than other languages, so if you dropped out of the sky with a few select phrases under your belt, you might feel like everyone is speaking in inside jokes or a secret code. And regardless where your next trip takes you, make sure you’ve mastered these 30 Major City Names You May Be Pronouncing All Wrong.

Thai difficult languages to learn

6
Thai

It isn’t the grammar that will bog you down when you’re trying to learn Thai, it’s the writing and the pronunciation, which has five different tones and long and short vowel sounds. The alphabet has a staggering 44 consonants and 32 vowels.

Icelandic difficult languages to learn

7
Icelandic

With four cases and three genders assigned to their words, as well as many letters unfamiliar to English speakers, Icelandic is no walk in the park to learn. Words can also be very long and deciphering how to pronounce them can defy intuition. It’s frequently listed as one of the more difficult languages to learn for English speakers. And for more fascinating facts about language, check out the 15 Hardest Words to Pronounce in the English Language. 

Estonian difficult languages to learn

8
Estonian

Estonian is the third and final language in that tricky class with Hungarian and Finnish on this list, and it’s packed with a whopping 14 noun cases. In addition to that, consonants and vowels have three distinct lengths: short, long, and overly long. But the fun doesn’t stop there.

The grammar is also loaded with exceptions, which might make you stop and rethink your desire to nail a language that only has 1.1 million native speakers to begin with. And, regardless of your language proficiency, when you’re eager to make your next trip more pleasant for everyone, avoid these 15 Things You Should Never Do On an Airplane.

Georgian difficult languages to learn

9
Georgian

Georgian has its own writing system that no other language uses. And a lot of the letters look surprisingly similar. For example, ვ, კ, პ, ჰ, ყ, ფ, გ, and ც are all different letters that you might have a hard time distinguishing between if you’re new to the game.

The pronunciation is also pretty challenging for native English speakers, and on top of that, so few people attempt to learn Georgian that finding a teacher—or native Georgians who can understand your garbled pronunciation—can be difficult.

Czech difficult languages to learn

10
Czech

Declension in Czech is its own special nightmare, but you won’t even need to worry about that until you get past the seemingly insurmountable hurdle that is pronouncing the words correctly. On the one hand, each letter only has one pronunciation ever. On the other hand, Čtvrtek means Thursday, and mastering the way each of those sounds works together is going to take you a while.

It’s helpful if you speak another Slavic language, but otherwise, it’s going to be a challenge. And if you’re wondering if the Czech Republic should be on your travel bucket list, check out these 37 Travel Destinations Every Man Over 40 Should Have Visited.

11
Albanian

Albanian’s 36-letter alphabet should clue you in that attempting to master this language is going to be a wild ride. In addition, the grammar is filled with exceptions to the rule that you’ll have to remember, too.

12
Turkish

Turkish is an agglutinative language, which means, in crude terms, that complex words are formed by tacking stuff on without changing the previous stuff at all. It is pretty foreign to English speakers, but if you speak Japanese, Korean, or Finnish (which are all also on this list), you won’t have such a hard time grasping it.

Polish difficult languages to learn

13
Polish

Compared to the Finno-Ugric languages on the list (Finnish, Hungarian, Estonian), the seven cases you have to contend with in Polish don’t seem too intimidating. The pronunciation is what will get you. There are a lot of sounds that simply aren’t present in the English language and require a lot of practice to master.

Navajo difficult languages to learn

14
Navajo

Navajo is hard enough to figure out that code talkers in World War II used the language to develop a code for communicating that the Germans wouldn’t be able to track.

Greek difficult languages to learn

15
Greek

The most obvious impediment to learning Greek is the alphabet. The grammar can also be a little tricky, with some unusual conjugations, lots of rules, and gendered nouns. And pronunciation requires some practice because there are sounds that don’t have an equivalent in English. There’s a reason “it’s Greek to me” is a common idiom for expressing confusion, after all.

Korean difficult languages to learn

16
Korean

In terms of learning to read, Korean has a relatively straightforward alphabet that doesn’t take too long to learn, unlike the characters used in Chinese and Japanese writing systems, so you can start sounding out words pretty quickly. But being able to speak is a completely different can of worms, thanks to grammar that is totally different from English and pronunciation that is laden with difficult-to-master rules.

Mandarin difficult languages to learn

17
Mandarin

Mandarin is one of the few languages ranked as the most difficult to learn for English speakers by the Foreign Service Institute. The alphabet is made of very elaborate characters; the language is tonal; there are lots of idioms, and the ability to speak the language doesn’t help you read it. Knowing how to read it doesn’t even particularly help learn how to write it. It’s not for the faint of heart.

Japanese difficult languages to learn

18
Japanese

The first obstacle to learning Japanese is the writing system, which will provide you no clues unless you also speak Chinese. The grammar seems like it’s very simple, but Japanese also uses particles, which are markers for parts of speech that do not have an English equivalent.

Cantonese difficult languages to learn

19
Cantonese

The tones in Mandarin make it a challenge for English speakers, but Cantonese has twice as many tones as Mandarin—eight in total. Because of its pictoral writing system, you aren’t going to be able to learn to read phonetically. In addition, because Mandarin is the simplified version of Cantonese and is widely used across mainland China, there simply aren’t as many resources for learning Cantonese.

20
Arabic

To learn Arabic, you have to learn a new alphabet, and get used to reading from right to left. A lot of the sounds in the language are difficult for English speakers to master, and the grammar is packed with irregular verbs. Even if you manage to overcome all of that, it is also a language with many, many dialects that vary widely. So, you might be able to get by in Jordan, but have a hard time in Kuwait.
