Every language has a fair share of irregularities. However, they normally represent only a small portion of the entire language. My mother tongue has at least 40% of irregularities. You can hardly find a language as difficult as it is. Have you ever met a native speaker who can’t even pronounce a common surname in their native language? Or people don’t know how to say lightening in their mother tongue? Can you imagine a word should be pronounced differently even in “the same context”. Or there exist massive amounts of tonal changes without reason？

Can you name a language which native speakers fail in daily-life scenarios? Yes. Taiwanese – a language in which native speakers cannot master colloquial speech. A language that native speakers stumble over common, non-technical terms. A language that native speakers fail to master tonal changes perfectly. And of course, a language that is drastically dying due to its incredible complexity.
