This is the 745th most frequent Lithuanian word.
jam
"Jam" in Lithuanian means "to him" (dative case of "jis").
'Jam' is the dative case of the masculine pronoun 'jis' (he), indicating the indirect object of the verb 'duosiu' (I will give).
Aš duosiu jam knygą.
I will give him the book.
'Jam' is used in this sentence in the dative case as part of the impersonal construction 'jam pavyko,' which translates to 'he succeeded.'
Jam pavyko pasiekti tikslą laiku.
He succeeded in reaching the goal on time.
'Jam' here is used as the dative case to indicate the recipient of the help.
