In this article, we look at the 25 most difficult languages to learn. You can skip our dive into the vast tapestry of human communication in which we focus on some of the hardest languages to master by heading over to the 10 Most Difficult Languages to Learn.

Learning a new language can be an arduous experience, especially with the challenges associated with complex grammatical structures, pronunciations, vocabulary, and the lack of opportunities available to communicate with native speakers of the language. However, the grind of delving into a new language does not go unrewarded and opens new avenues and opportunities for the learner.

Since English is the lingua franca at the global stage, in most cases you would do fine with your ability to communicate in this language, but with rapid pace at which globalization is taking place and more corporations setting up their facilities in foreign markets, mastering a new language can help individuals navigate language barriers and succeed at what they have set out for.

According to projections, 13 of the 20 Largest Economies in the World in 2050 will be Asian and African countries, and in many of these English language is not a strong suit. Already, several large western corporations have begun outsourcing their operations to these countries, especially China and India, in anticipation of the radical shift in the global economic order that awaits us in the next few decades.
