Pāṇini sūtras

The Personal-endings and their substitutes (III.2.121-120) are, when they are sârvadhâtuka (III.4.113 &c), unaccented, after the characteristic of the Periphrastic future (tasi), after a root which in the Dhâtupâtha has an unaccented vowel or ṅ (with the exception of hnuṅ and iṅ) as indicatory letter, as well as after what has a final a in the Grammatical system of Instruction (upadeśa).

German Die Personalendungen und ihre Substitute (s. 3, 2, 124-126) sind, wenn sie sārvadhātuka heissen (s. 3, 4, 113 fgg.), unbetont nach dem Charakter des periphrastischen Futurums, nach Wurzeln, die im Dhātupāṭha einen unbetonten Vocal oder ein ṅ (jedoch mit Ausnahme von hnu und i Med.) zum stummen Laute haben, sowie nach einem im grammatischen Unterrichtssystem auf a auslautenden Tempusstamm.
