Mahavyutpatti (Skt. Mahāvyutpatti; Tib. བྱེ་བྲག་ཏུ་རྟོགས་པར་བྱེད་པ་, Wyl. bye brag tu rtogs par byed pa) — the famous glossary of Sanskrit and Tibetan terms completed during the reign of King Tri Ralpachen in order to standardize translations. Ralpachen is said to have ordered a meeting of scholars in 921, and charged them with providing standard Tibetan equivalents for a wide range of terms encountered in Sanskrit Buddhist texts. The result was the Mahavyutpatti.
