This is the 121st most frequent Polish word.
niego
The Polish word "niego" means "him" or "of him" when referring to a male in genitive or accusative contexts.
In this sentence, 'niego' is used as the objective form of 'he' (on) in a context requiring the genitive case after the preposition 'od'.
Lubię słuchać opowieści o nim, bo wiele od niego się nauczyłem.
I like listening to stories about him because I learned a lot from him.
Here, 'niego' serves to replace 'him' in an emphatic manner after the preposition 'o', which prompts the genitive or accusative case.
Nie mogę przestać myśleć o jego słowach i o nim samym.
I cannot stop thinking about his words and about him himself.
In this example, 'niego' is employed in the accusative case form of 'he' after the preposition 'na', indicating direction.
