I guess Finnish is very hard language to learn.. So many things are so different. Like in english you put 'a' or 'an' or 'the' before some words.
In swedish there's 'en' and 'ett'. But we don't have anything like that in Finnish.
(so I guess I do many mistakes with those. ^^;
And you say 'my book', or anything else with that word 'my', we can say it with just one word. But you can also say with two words.
a book = kirja
my book = (minun) kirjani
your book = (sinun) kirjasi
her/his book = hänen kirjansa (we have just one word, same to women and men. and here you need two words.)
our book = (meidän) kirjamme
your book = (teidän) kirjanne (and we have two different words as 'you'. that first one was about just one person, and this is about more people.)
their book = heidän kirjansa (here's also two words needed.)
also same kinda thing with "me" "you" "her / him" "us" "you" and "them".
And in english it matters where in sentence you put words. In finnish it's different.. We have another order.. and still there's many ways to use same words sometimes..
Oh well this was kinda pointless I guess.
