"Nie znamy tamtej dziewczynki."

Translation: We do not know that girl.

[Jesuis89]

I thought dziewczynki was plural?

[tadjanow]

In this sentence it's genitive singular.

Thanks for the link to the Wiki dictionary.

[Travelinkid]

me too

[A477]

if it was plural it would be tamtych dziewczynki, right?

[Jellei]

It would be "Nie znamy tamtych dziewczynek" (see the link in the comment before yours)

[A477]

oh yes genitive right, thanks :)

[Yumiifmb]

Is there an explanation on when is genetive used ? There doesn't seem to be any notes available on this skill.

[Garinlelorain]

I thought "dziewczynka" was for "little girl" and dziewczyna" for "girl" but here "little girl" is wrong. Have I misunderstood something ?

[arminia11_web_de]

Bueller? Bueller? Anyone?

[Jellei]

"little girl" currently works.

[YoMTXU]

Why tamtej?

[icha1221]

In negative sentence tamte becomes tamtej

[duoitaliano]

How would you say "We do not know THIS girl"?

[Jellei]

"Nie znamy tej dziewczynki".

[11fifififi11]

I know everything

[Jellei]

Congrats!

Why would anyone make their language so complicated. How is it possible to remember all these case variations for every word?

[Jellei]

It's pretty obvious when you learn it as a child, as a native. It's not like we actually remember the variations (ok, sometimes we need to), it's rather that we feel it. Just like you feel like your language (I assume English) works, while a lot of things are super weird to the learners.
