Monosyllabic stems have the regular accent of such, throwing the tone forward upon the endings in the weak cases.

a. But the accusative plural has its normal accentuation as a weak case, upon the ending, in only a minority (hardly more than a third) of the stems: namely in datás,pathás, padás, nidás, apás, uṣás, jñāsás, puṁsás, māsás, mahás; and sometimes in vācás, srucás, hrutás, sridhás, kṣapás, vipás, durás, iṣás,dviṣás, druhás (beside vā́cas etc.).

b. Exceptional instances, in which a weak case has the tone on the stem, occur as follows: sádā, nádbhyas, tánā (also tanā́) and táne, bā́dhe (infln.), ráṇe andráṅsu, váṅsu, sváni, vípas, kṣámi, sū́rā and sū́ras (but sūré), áṅhas, and vánas and bṛ́has (in vánaspáti, bṛ́haspáti). On the other hand, a strong case is accented on the ending in mahás, nom. pl., and kāsám (AV.: perhaps a false reading). And preṣā́, instr. sing., is accented as if préṣ were a simple stem, instead ofpra-íṣ. Vimṛdháḥ is of doubtful character. For the sometimes anomalous accentuation of stems in ac or añc, see 410.
