1939 Jrnl. Amer. Oriental Soc. 59 159 Ordinarily, the Hindu metricians mechanically define any metrical pāda of eleven syllables as ‘trisṭubh’, and any of twelve syllables as ‘jagatī’. This cannot be accepted... What we shall call a trisṭubh may have anywhere from ten to thirteen syllables, a jagatī from eleven to at least thirteen (possibly more). The distinction between the two is solely based on the cadence; a trisṭubh always ends ˘¯^x..in western terms..in a catalectic diiambus.
