The Altindische Grammatik is the monumental Sanskrit grammar by Jacob Wackernagel (1853-1938), after his death continued by Albert Debrunner, published in Göttingen between 1896 and 1957. The work presents a full discussion of Sanskrit phonology and nominal morphology, but a treatment of the verb is lacking. A fourth volume covering the verb was in preparation by Karl Hoffmann but was never published, and to this day (the 2000s), a thorough discussion of the Sanskrit verbal system is lacking.
