>>11333140Agglutination allows limitless vocabulary with maybe several thousand of actual, memorized vocabulary. Chinese uses only little over 3000 in practice, there are some non obvious common combinations and there are characters with different readings, but the whole language consists of let's say 4000-5000 vocabulary. With this (in English preschooler level) vocabulary, it can discuss anything, from everyday topics like buying new clothes, to specialized, like the latest treatment for cancer. So agglutination greatly reduces the amount of vocabulary that is needed, since most concepts can be combined from common words. Some langauges extend this to grammar, but Chinese doesn't.
Languages with evidentiality force you to indicate what evidence you have for what you are saying. e.g. "There are alien bases on the moon" would be said differently if you saw it with your own eyes, if you derived it from idirect evidence, if somebody told you, etc.
