We are taught to categorize everything in life from a young age. It’s either easy or difficult, good or bad, or fun or boring. It’s the same with languages and learning a new one. 

While you may believe you either learn an additional language with ease or you don’t, it’s not that simple. 

The difficulty level of a particular language actually depends on you, and it’s based on factors like your native language, whether you have a talent for mastering new tongues, your goals and motivations, how much time and effort you put into studying, and the quality of the language course and material.

The Foreign Service Institute (FSI) categorized languages based on how easily US diplomats mastered the new language.

 All of the most challenging languages to learn for English natives fall in Category IV and V, requiring a minimum of 44 to 88 weeks to reach speaking and reading proficiency level 3.

I have compiled a list of the languages that are generally considered to require more blood, sweat, and tears to learn, but remember that how challenging a language is to learn is completely relative to you.

Learning a tonal language can be intimidating since the pronunciation and inflection of a word significantly influences the meaning.

Chinese

# of global speakers: 1.35 billion

Official Chinese-speaking countries: China, Singapore, and Taiwan

Chinese is one of the oldest written languages, with a history that spans 6,000 years. However, Standard Chinese was only officially adopted in the 1930s.

Mandarin Chinese, like its Cantonese counterpart, may be challenging to learn.

Reasons why Mandarin Chinese is challenging to learn:

  • The Writing System

Instead of using the Latin Alphabet that English-natives are familiar with, Chinese doesn’t have an alphabet. Instead, the language comprises one-syllable characters or logograms, called hànzì or Han characters, which infers meaning, not sound.

A single character or combinations thereof make a Chinese word. There are over 100,000 characters, and a Chinese language-learner needs to know at least 200 characters to navigate common situations like ordering at a restaurant and 2,000-3,000 characters to read the newspaper.

Of course, you’ll start with pinyin, which uses Latin letters to teach you Mandarin phonetically. And you can choose to learn simplified or traditional Chinese characters. 

  • A Tonal Language

Learning a tonal language can be intimidating since the pronunciation and inflection of a word significantly influences the meaning. Mandarin has 4 tones: the level tone (píng), rising tone (sháng), departing tone (qù), and final tone (rù). For example, “ma” or mā, mà, mǎ, and má can mean mother, numb (or hemp or fiber), horse, or scold respectively. 

To become conversational in Mandarin, you’ll need to fine-tune your hearing and speaking skills to get the tones right.

  • Idioms

With centuries in the making, it’s no surprise that the Chinese have cultivated a rich usage of idioms. In fact, there are between 5,000 to 20,000 Chinese idioms you can learn.

Russian

# of global speakers: 260 million

Official Russian-speaking countries: Russia, Belarus, Kyrgyzstan, and Kazakhstan

The Russian language originates from the Proto-Indo-European language, and the East Slavic language is about 4,000-6,000 years old.

Reasons why Russian is challenging to learn:

  • The Writing System

Russian uses the Cyrrilic alphabet, and while that’s not as challenging as the Chinese Han characters, it is still different from the Latin alphabet English natives are used to.

There are 33 letters in the Cyrrilic alphabet (6 of these are the same as the Latin alphabet), and each is phonetic. However, at first, the letters can look very similar to each other, but it’ll get easier the more you get used to them.

On the other hand, Russian cursive may make you want to cry.

  • Pronunciation

There is no correspondence to the letters and sounds they represent, which makes pronouncing words in Russian challenging. The good news is there are rules, making learning Russian easier. 

The language also has “soft” and “hard” pronunciations, determined by the vowel that follows the consonant.

  • Complex Grammar

Russian grammar is complex. For example, the language has 6 cases, meaning the words change depending on their role in a sentence, and 3 genders (female, male, and neutral). There are also verbs of motion, animate and inanimate nouns, and no articles (a/an/the).

Finnish

# of global speakers: 5 million

Official Finnish-speaking countries: Finland

Experts think that Sami, which originated in 1,500 BCE, is the origin language of Proto-Finnic, which then later became the Baltic-Finnic languages, from which Finnish came to be. The history of Finnish can be traced back to more than 3,000 years ago.

Reasons why Finnish is challenging to learn:

  • Complex Grammar

One of the main aspects that makes Finnish such a hard language to learn for English speakers is the complex grammar that can be quite intimidating. The word order in sentences is confusing, and since many Finns don’t even follow the rules, understanding what’s being said is daunting in the least. 

For example, there’s no future tense, and you’ll have to rely on context to discern whether the speaker is talking about the present or future. There are also 15 cases and no articles. 

Suffixes change the meaning of the word. “Yhdysvallat” means the United States and “Yhdysvalloista” means “from the United States.” Suffixes can also be used to form a question: “on” means “is” and then “onko” means “is it?”

  • Pronunciation

This aspect of the Finnish language may not be tricky, but it can be, depending on how easily you master vowel harmony. Non-compound words in Finnish can only contain ä, ö, or y (front vowels) or a, o, u (back vowels), while the neutral vowels of “e” and “i” can mix with the front and back vowels.

  • Vocabulary 

Finnish doesn’t share any similarities with English words, so the vocabulary will be new. You can join words (like “siskonis” – sister – and “tytär” – daughter – to make “siskontytär” – niece) and add endings to make new ones.

Arabic

# of global speakers: 372.2 million

Official Arabic-speaking countries: Algeria, Bahrain, Comoros, Djibouti, Egypt, Iraq, Jordan, Kuwait, Lebanon, Libya, Mauritania, Morocco, Oman, Palestine, Qatar, Saudi Arabia, Somalia, Sudan, Syria, Tunisia, the UAE, and Yemen

Arabic, a member of the Semitic language family, originated in the northwest of the Arabian Peninsula. The language dates back to the 8th century BCE.

Reasons why Arabic is challenging to learn:

  • The Writing System

Not only does Arabic use a completely different writing system compared to English, but the language is also written and read from right to left.

There are 28 letters in Arabic script, and some can have as many as 4 forms.

  • The Absence of Short Vowels

Short vowels are omitted from words, except in children’s books and beginner Arabic language books. However, they are presented as diacritical marks, called Harakat, that are written above or below a letter.

They are critical in Arabic since the diacritics influences how a word is pronounced and understood. Incorrectly identifying the Harakat can completely change the meaning of a word.

Long vowels can have a double function (vowel vs consonant) depending on the letters before them.

  • Complex Grammar

Arabic has a complex grammar system. The language has singular, plural, and dual forms, 12 personal pronoun forms, a different sentence structure where the verb comes before the subject, masculine and feminine nouns, and conjugations so the verb matches the subject plurality and gender.

Icelandic

# of global speakers: 366,000

Official Icelandic-speaking countries: Iceland

The origins of Icelandic can be traced back to Old Norse, which was spoken in the 9th century. The Icelandic Sagas, some of the oldest preserved texts, were written in the 13th and 14th centuries.

Reasons why Icelandic is challenging to learn:

  • Spelling

Icelandic uses a writing system that’s similar to the Latin alphabet. The language has 32 letters, so some are completely new to an English native. For example, the “ð” and “þ” are similar to the English unvoiced and voiced “th” sounds in “father” and “thick,” respectively.

You must also learn the pronunciation rules, and how the letter is pronounced depends on its location in a word.

  • Very Few Loanwords

While many languages across the world love to borrow words from other tongues, Icelanders are very proud of their language and try their utmost to avoid including loanwords in Icelandic. For example, “jeans” are simply “jeans” in many non-English languages, but in Icelandic, “jeans” are “gallabuxur.”
