Which is the most difficult languages in the world? It's ǃXóõ. Depending on the dialect, there are 80-160+ consonants, which includes most consonants humans can pronounce, and 70% words are starting in a click sound. It's a tonal language that has 2-4 tones. It's a good language to practice pronunciation. 😆 (It's real. Some material of this language is used to train the phonetics students, you can find that in the material I posted before. ) The youtuber sometimes laughed without control during the introduction. 😄 The main actor of The God's Must be Crazy, whose name is Nǃxau ǂToma, speaks Juǀʼhoan language, which is similar to ǃXóõ, shown in the film series.
