To make it easier, we’ve rounded up a list of the most useful languages to learn in the world, whether you’re aiming to boost your career, travel the world, or build meaningful connections in the future. It’s time to separate the wheat from the chaff and focus on languages that pull real weight!
1. English
Which language is most beneficial to learn? Starting with the undisputed global language of business, science, and popular culture, English is one of the best languages to learn.
With over 1.5 billion speakers worldwide,[1] English is a non-negotiable skill for anyone aiming to stay on the global radar. Whether you’re climbing the corporate ladder, diving into the world of tech, or navigating the waters of international diplomacy, English is the key that unlocks countless doors.
2. Chinese
If you’re thinking about the best languages to learn for the future, Mandarin Chinese should be at the top of your list.
With China’s expanding role on the world stage, Mandarin has become more than just a useful language. It’s the second most spoken language globally and dominates nearly a quarter of internet usage.[2]
3. German
As the world’s third-largest economy, Germany plays a significant role in global industry; therefore, learning German is more than a good idea —it’s a decisive move.[3]
Speaking their language gives you a strong edge across Europe’s tech-driven markets, particularly if you aim to break into sectors such as engineering, automotive, or science.
4. Arabic
Arabic is one of the best languages to learn to make money, especially as it’s the official language in over 20 countries, including Egypt, Saudi Arabia, the UAE, Qatar, and Morocco. Mastering it gives you direct access to rich cultures, fast-growing markets, and expanding business opportunities across the Middle East and North Africa.
This region also emerges as a global hotspot for tourism and international affairs. With countries like Morocco, Egypt, and Tunisia drawing more global attention, Arabic is a strategic asset for anyone aiming to connect with one of the world’s most influential and dynamic regions.
5. French
While French is often referred to as the language of love, its global significance extends far beyond romance.
It serves as the official language in 29 countries, including key players such as Canada, Switzerland, and Belgium, and is a vital language for international organisations like the UN. For those dreaming of a career in diplomacy, high fashion, or the culinary arts, French is an invaluable skill.
6. Japanese
From the cutting-edge world of robotics and luxury consumer goods to the global phenomenon of anime, Japan is a leader in both innovation and culture.
Learning Japanese provides a direct connection to this dynamic society and its rapidly expanding economy. It’s a challenging yet highly rewarding language, and it’s easily one of the best languages to learn for jobs in tech, business, and animation.
If you’re learning English, you might wonder: what’s the most useful language to learn after English?
The answer depends on your goals. Want a career boost? Try Mandarin or German. Into culture and travel? Arabic or French could be it. Fascinated by tech or media? Japanese is a strong choice. But here’s the truth: whatever you pick, you should start with solid English.
