1. An apostrophe-like sign placed after a letter (also known colloquially as a chupchik):
   • as a diacritic that modifies the pronunciation of some letters (in modern Hebrew),
   • as a diacritic that signifies Yiddish origin of a word or suffix,
   • as a punctuation mark to denote initialisms or abbreviations, or
   • to denote a Hebrew numeral.
2. A note of cantillation in the reading of the Torah and other Biblical books, taking the form of a curved diagonal stroke placed above a letter.
