Male, female, neutral and none (ham, hende, den, det). Technically the last one isn't a sex but it still has its own word. A boy is male, a girl is female, a car is neutral and a house is neither. Nobody can explain the difference between the last two and therefore "none" is dying.
This has sense for me . Maybe "den" is used for "animated" , mobile things and "det" for static things.
Just like it can be hard to explain neutral ("it") to someone with a language with only he and she.
German is even more funny because they got three sexes: A boy is male, most animals are female and a girl is neutral.
The above things can't be explained logically they just are there for historical reasons.
Neutral gender has its historical roots in the ancient roman latin language , which has 3 genders : male, female , neutral and names have cases ( nominative, genitive, accusative , vocative , ablative ) which makes it a language with a strict logic.
I've studied it for 5 years at high school back in the days , and surprisily at a scientific oriented high school. When I've tried to understand why we studied 5 years this ancient language at a scientific oriented school , it seemed to not find any reasonable enough motivation for that.
For sure the influence of the Roman Church gives a lot of contribution for mantaining it and so also for studing of the Roman law which is the base of our juridic system.
But by a scientific point of view , there are at least two reasons for studing it :
- the strict logical structure of the language , which makes the language itself a good mental train for building logical processes.
- because the Roman Latin was the official language for international scientific pubblications and it was replaced by english language only in the 20th century. If you want to read the original Galilei's or Newton's pubblications you need to know Roman Latin language.
Of course this has not any sense for the mass of "the inter<<D>>et people" or even all the "post-'89" european generations, it's waste, spam for the other side of the Atlantic ocean.
