Every language has some unique features that strikes to you odd at first, but then once you get used to it, makes lot of sense. Take Spanish, for instance. It is took me a while to get used to almost complete absence of the pronouns: I, you and we. Since the verb form changes with the personal pronoun, one can easily understand who the text is referring to.
tengo - (I) have tiene - (you) have tenemos - (we) have
Efficient, isn't it?
I wonder why German that has similar verb form did not go the same way. Is it because Germans prefer order? Perhaps. It is definitely worth exploring the relation between general characteristics of a nation and the language.
Well, I guess that's the way a language evolves. It grows naturally. No wonder why artificial language like Esperanto could not grow into a world language despite numerous attempts in the past.
