A Complete Guide to the Most Spoken Languages in the World, Their Global Reach, and Why You Should Learn Them

Language is the bedrock of human civilisation. Languages shape economies, politics, culture and connection in every continent and culture. But not all languages are equal on the world stage, in a more and more interconnected world. Some have gone on to become real world languages, tools of international diplomacy, business, science and culture.

If you are a student looking for the best languages to learn, a professional considering languages for international careers, or just a curious polyglot, knowing which languages are most influential globally is very helpful. In this guide, we’ll look at the top 12 languages in the world today — ranked by a combination of native speakers, total speakers, geographic spread, economic power, and cultural impact.

What gives a language global impact?

Before we get into the list, it’s worth knowing what makes a widely spoken language different from a truly influential one. The languages you need to learn are not always the languages with the most native speakers – influence is multidimensional:

• Number of native and total speakers in the world

• Language of official use in several countries

• Application in international business, science and diplomacy

• Export of culture – film, music, literature, media

• Global growth trajectory and number of new learners

• The international organizations and the governance role

With that context in mind, here are the 12 most influential languages in the world today.
