Chinese use compound words a lot. For example, there is "午餐", which means "Lunch", where "午" means "noon" and "餐" means "meal". In this way, it is more like German "Mittagessen" where "Mittag" is "noon" and "Essen" is "eating".
There are also a lot of words do not make sense like "天真", which means "naive", while "天" means "sky" and "真" means "real(ly)". This does not make sense at all.
Still, most of the words are just between these two categories. For example "自然" means "nature", and "自" means "itself" and "然" means "happened". So "nature" means "it just happened itself". This is kind of make sense somehow but it is actually pretty blurred for most people.
