what do you think about it?
I forgot to answer this part.
I think it's amazing that people can converse without opening their mouths. :)
I have a theory about why the language developed in such a closed mouthed way and it is this...
Being a very cold climate in winter, opening the mouth wider to speak would involve more heat loss to the body. So a fairly closed mouthed language evolved.
...it's probably a heap of crap, but I'd love to hear other people's ideas.
What else do I think about it? I think agreement and declension suck, but I've tried to learn Polish like a child learns language, by absorption of whole phrases rather than consciously thinking about cases and genders. (Conversely, it takes a very gifted Pole to be able to get definite and indefinite articles in the right places in English. You can spot the non-natives on this forum very easily on that alone - but fair play to them for posting - I wouldn't be able to post decent quality written Polish).
The adult way of learning a language might be faster (vocab and grammar) but that's not how we teach our kids to speak natively is it? At least, not until they reach school age.
My son (almost 7) has been brought up "one parent, one language" from birth. He often corrects my Polish, but I can still get him sometimes. For example, the other day I told him "Kuba is short for Jakub". He disagreed with me. "No it's not". I said "Let's ask Mummy" ;)
Dad was right. I still know more than him about tennis, photography, building etc. But how long will it last?
