My language would force me to tell you whether or not this was an uncle on my mother's side or my father's side, whether this was an uncle by marriage or by birth, and if this man was my father's brother, whether he was older than or younger than my father.
Język kazałby mi uściślić, czy wujek jest ze strony matki czy ojca, czy to krewny czy powinowaty, a jeśli to brat mojego ojca, to czy jest starszy czy młodszy.
