I am from Finland som i speak Finnish dayly. Finnish is an uralic language totally different from English, german or Any latin language like french or spanish.
There Are many strange Words in Finnish.
One of THE Strangers Words in Finnish what i think is the word "hänhän"
hän in English means the third person of The personal pronomen like he/she. So hänhän means hehe or sheshe in English.
In Finnish we do not use genus like german or french. So in Finnish language there is No der, das oder die or a, an. In Finnish we do not say a table, Finns just say table.
Then to express
On (The) table
By (The) table
Off(the) table
Of (The) table
That is totally another chapter of Finnish grammar.
The second hän in The word "hänhän" is a preffix added to The first hän. In Finnish we use other Words with The preffix hän words like
mikä-hän,minä-hän,tämä-hän,ei-hän and so on
Moikka ja hyvää yötä
