ucznia

"Ucznia" is the genitive or accusative singular form of "uczeń," meaning "student" or "pupil" in English.

Here, 'ucznia' is the accusative singular form of 'uczeń', correctly used as the direct object of the verb 'widzę'.

Widzę ucznia w klasie

I see a student in the class

In this sentence, 'ucznia' again is in the accusative case, functioning as the direct object of the phrase 'Podszedłem do'.

Podszedłem do ucznia i zapytałem o zadanie

I approached the student and asked about the homework

Here, 'ucznia' is part of a negative sentence and remains in the accusative case as per the grammatical rule in Polish where the accusative changes to the genitive in negative contexts involving direct objects.

Nie znam dobrze tego ucznia

I don't know this student well
