"Vidím malého koně."

Translation: I see a small horse.

[AntonioBuc16]

Why is it malého and not malé in this case? Malého means it is singular?

[Takis007]

Yes.
Vidím malého koně - one horse.
Vidím malé koně - two (three, four) horses

[J_Par]

This looks like it's in genitive case. Why?

[Nemesis_NaR]

No, it's accusative. But genitive looks exactly the same that's true.

[J_Par]

Ok, thanks! That makes sense.

[SeanMeaneyPL]

Accusative plural would be Vidim malé kone, I suppose?

[Takis007]

Vidím malé koně.

[SeanMeaneyPL]

Yes, thanks. I can't make the inverted circumflex on the e, unfortunately.

[NeilMcQ]

It's called a haček :-)

[Takis007]

Not "haček" but "háček" :-)

[OliviaSilber]

How do I know that it's singular and not plural? Through the adjective?

[SeanMeaneyPL]

Exactly.

[HKF2006]

So is this plural or singular? Thanks :)

[BoneheadBass]

It is singular; malého is the clue, as earlier comments have indicated. It¨s often very helpful to read the existing discussion.

[404Error_]

Isn't "maleho" the genitive form of maly?

[VladaFu]

Please read the existing before asking. See the question of J_Par.
