New study measures grammatical complexity of languages
As a Thai, I’m somewhat proud to see that our gramma is quite simple, i.e. no tenses and genders, etc. These extra structures are superfluous if you think about it. This makes it easy for beginners to start forming simple sentences. However, the complexity gets pushed to the vocabulary. It tends to have different words that mean the same thing, but with differing levels of, say politeness. Not to mention a whole ton of slang and double meanings.
