Certain roots in ā weaken the ā in middle inflection to i (as also in the root-aorist: above, 834 a): these are said to be sthā, dā, and dhā; in the older language have been notedádiṣi and adiṣata from √dā give (and adiṣi perhaps once from √dā bind), adhiṣi and adhiṣata (with the optative dhiṣīya) from √dhā put, and asthiṣata; also agīṣṭhās andagīṣata from √gā go (with adhi).

a. The middle inflection of the aorist of √dā would be, then, according to the grammarians: ádiṣi, ádithās, ádita; ádiṣvahi, ádiṣāthām, ádiṣātām; ádiṣmahi, ádiḍhvam, ádiṣata.
