There is a lot of poor translation in the titles and subtitles of Satyajit Ray’s movies.
In particular, Apur Samsar is translated as The World of Apu, which fails to capture most of the meaning of samsar (pronounced “shong-shar”). While it does literally mean “world,” when you speak of a particular person’s samsar, the usual meaning is his adult life, which includes a wife, a separate household, and children. An unmarried man would never be spoken of as having a samsar.
