Cases in Slovak
Niekto je otcom toho chlapca - means - Someone is a father to that boy.
... As I see it, "otcom" is in Instrumental, "chlapca" is in Acusative, but I don't know in what case is personal pronoun "toho", and I would like to see how that personal pronoun changes throughout cases in Slovak.
N: ten chlapec
G: (od) toho chlapca
D: tomu chlapcovi
A: toho chlapca
L: (o) tom chlapcovi
I: (s) tym chlapcom
its just a coinsidence that G and A have the same form. In feminin it wouldnt be the same
