Official transliteration guide for Yiddish according to the YIVO, the Official Yiddish Language Academy.
EXCEPTION: When the word אויף is used as a preposition, it is pronounced and therefore transliterated as af (not oyf), following modern convention.
*Yiddish consonants with checkmarks occur only in words of Hebrew or Aramaic origin.
This chart is based on the Yiddish Alef-Beys (Alphabet) of the YIVO Institute for Jewish Research, and on Sten Vikner’s Yidisher Alef-Beys, which also includes handwritten letter forms, phonetic charts, and a chart of dialect differences.
