I've been learning a few interesting Yiddish words while reading an American Family by Peter Lefcourt:
Golem: Jewish Folklore, a figure artificially constructed in the form of a human being and endowed with life.
Here is how golem was used on page 86:
And to people who were both old and Jewish he became a sort of golem, returned to earth to avenge two thousand years worth of persecution and indignity.
Tsuris: (Yiddish) aggravating trouble.
Here is how tsuris was used on page 98:
And the one thing that Meyer Perl did not want at this stage of his life was tsuris.
This is a fun book to read so far as the author does a wonderful job of setting up the time period. He creates some great pictures for us to imagine!
