a. By the suffix dā are made adverbs of time, but almost only from pronominal roots.

b. Thus, tadā́, yadā́, kadā́ (in RV. also kádā), idā́ (only in V.); and sádā, beside which is found earlier sádam. Besides these, in the older language, only sarvadā́; later a few others, anyadā, ekadā, nityadā. A quasi-locative case use is seen occasionally in such phrases as kadācid divase (R.) on a certain day.

c. By the perhaps related dānīm are made idā́nīm, tadā́nīm, viçvadā́nīm, tvadānīm (toneless). Viçvadā́ni occurs as adjective in TB.

d. With rhi are made, from pronominal roots, tárhi, etárhi, yárhi, kárhi, amúrhi.

e. The suffix di, found only in yádi if, is perhaps related with dā, in form as in meaning. Sadadí (MS.) is of doubtful character.
