Why is it malého and not malé in this case? Malého means it is singular?
Vidím malého koně - one horse.
Vidím malé koně - two (three, four) horses
This looks like it's in genitive case. Why?
No, it's accusative. But genitive looks exactly the same that's true.
Ok, thanks! That makes sense.
Accusative plural would be Vidim malé kone, I suppose?
Vidím malé koně.
Yes, thanks. I can't make the inverted circumflex on the e, unfortunately.
It's called a haček :-)
Not "haček" but "háček" :-)
How do I know that it's singular and not plural? Through the adjective?
So is this plural or singular? Thanks :)
It is singular; malého is the clue, as earlier comments have indicated. It¨s often very helpful to read the existing discussion.
Isn't "maleho" the genitive form of maly?
Please read the existing before asking. See the question of J_Par.
