As an English speaker, how long do you think it would take you to learn a new language? Well, it depends on the language you’re trying to learn. Still, you can get a good idea from the Foreign Service Institute language difficulty ranking, which shows how difficult different languages are for English speakers to learn.
In this post, we’ll take a closer look at the FSI language difficulty ranking and how it works. We’ll also find out which languages are considered the easiest and hardest for English speakers. Let’s dive right in!

The FSI language difficulty ranking is a system that shows how difficult different languages are for English speakers to learn. It was developed by the United States Foreign Service Institute (FSI) to help estimate how much time English-speaking diplomats may need to learn a foreign language.
Now, there’s an emphasis on “English-speaking diplomats.” The reason for that is that the FSI ranking is specifically based on English speakers learning other languages. It does not mean that a language is objectively easy or difficult for everyone.
So, the relationship between your mother tongue and the language you want to learn can make learning that new language faster or slower than the FSI estimated. Your previous language-learning experience, study habits, exposure to the language you’re trying to learn, and other factors can also affect how quickly you learn it.
How Does The FSI Rank Languages By Difficulty?
The FSI ranks languages by estimating how much time English speakers need to reach a professional level of proficiency. The more time a language generally requires, the higher its difficulty category.
To create its categories, the FSI considers how different a language is from English. They look at how different the vocabulary, grammar, pronunciation, writing system, and overall structure are from the English language. If a language is very different, it’s usually classified as hard. And if there’s a high degree of similarity, then it’s easier.
What Are The FSI Language Difficulty Categories?
The FSI language difficulty categories are four: Category I, II, III, and IV. Category I contains the languages that are generally the easiest for English speakers to learn, while Category IV contains the hardest.
Here are the four FSI language difficulty categories:
| FSI Category | Difficulty Level | Estimated Study Time | Examples of Languages |
|---|---|---|---|
| Category I | Easiest | 24–30 weeks (552–690 class hours) | French, Spanish, Romanian, Dutch, etc. |
| Category II | Relatively easy | Around 36 weeks (828 class hours) | German, Malay, Swahili, Indonesian, etc. |
| Category III | Hard | Around 44 weeks (1,012 class hours) | Albanian, Bengali, Bulgarian, Finnish, Hindi, etc. |
| Category IV | Super-Hard | Around 88 weeks (2,200 class hours) | Arabic, Japanese, Korean, Mandarin, Cantonese, etc. |
Category I languages are generally closer to English in terms of vocabulary, grammar, and other linguistic features. Meanwhile, Category IV languages are very different from English.
What Are The Easiest Languages To Learn?
According to the FSI language difficulty ranking, the easiest languages to learn for English speakers are generally the Category I languages, which include Spanish, French, Italian, Portuguese, Dutch, Romanian, and several others.
These languages share similarities with English. For example, English and French have many words with similar origins, while Spanish and Italian have relatively familiar alphabets and sentence structures for English speakers.
However, how easy a language will be for you as a learner also depends on other factors. These include:
- Your native language: If your first language is similar to the language you are learning, you may find it easier.
- Previous language-learning experience: If you already speak more than one language, learning another one may also feel more familiar.
- Exposure to the language: When you’re regularly hearing and using a language through conversations, music, movies, or other media, it can make learning easier.
- Time and consistency: The amount of time you dedicate to studying and practicing the language regularly, and how frequently you do it, can make a big difference in how quickly you progress.
- Motivation: If it’s a language that you’re genuinely interested in, it will be easier to stay committed to learning it.

What Are The Hardest Languages To Learn?
According to the FSI language difficulty ranking, the hardest languages to learn for English speakers are the Category IV languages. These include Mandarin Chinese, Cantonese, Japanese, Korean, and Arabic. These languages are very different from English in areas such as grammar, pronunciation, vocabulary, writing systems, and sentence structure.
However, just like with easier languages, factors such as your exposure to the language, time and consistency, learning environment, etc., can also influence how quickly you learn a difficult language.
