dziewczynkę
"Dziewczynkę" means "girl" (accusative or diminutive form) in English.
In this sentence, 'dziewczynkę' is in the accusative case, as it is the direct object of the verb 'widzę' (I see).
Widzę małą dziewczynkę bawiącą się na podwórku.
I see a little girl playing in the yard.
Here, 'dziewczynkę' should be in the dative case instead of the accusative case due to the preposition 'dla' (for). The correct form would be 'dziewczynki' in the dative case.
Mam prezent dla dziewczynkę z sąsiedztwa.
I have a gift for the girl from the neighborhood.
In this sentence, 'dziewczynkę' is in the accusative case governed by the preposition 'o' (about), describing the girl mentioned in the story.
