the accent is allowed to fall on any one of the syllables of the word, and the root-syllable if unaccented has sometimes the weak form (namely, in contracted stems with e for medial a: below, 794 e; and in certain other verbs, as vivijitha). The earlier language, however, affords no example of a 2d sing., whatever its ending, accented on any other than the radical syllable, or failing to conform to the rules of strengthening as given above (in a, c, e).
h. Occasional instances of strengthening in other than the singular persons are met with: thus, yuyopima and viveçus (RV.), pasparçus (KeU.), and, in the epics, cakartus and cakartire, cakarṣatus, jugūhire, nanāmire, bibhedus, vavāhatus, viveçatus, vavarṣus. The roots dṛ, pṛ, and çṛ, and optionally jṛ, are said by the grammarians to have the strong stem in weak forms; but no examples appear to be quotable. AV., however, has once jaharus (probably a false reading); and in the later language occur caskare (√kṛ scatter) and tastare.
i. The root mṛj has (as in the present-system: 627) vṛddhi instead of guṇa in strong forms: thus, mamā́rja; and √guh (also as in present: 745 c) has ū instead of o (but also juguhe E.).
794. As regards the weakening in weak forms:
a. It has been seen above (783 b) that roots beginning with i or u fuse reduplicating and radical syllable together to ī or ū in the weak forms; and (784) that roots contracting va and ya to u or i in the reduplication do it also in the root in weak forms, the two elements here also coalescing to ū or ī.
b. A few roots having ya and va after a first initial consonant, and reduplicating from the semivowel (785), contract the ya and va to i and u: thus, vivic from √vyac, vividh from √vyadh (but vivyadhus MBh.), suṣup from √svap. The extended roots jyā, pyā, vyā, çvā, hvā show a similar apparent contraction, making their weak forms from the simpler roots jī, pī, vī, çū, hū, while hvā must and çvā may get their strong forms also from the same (and only jijyāú is quotable from the others).
c. The root grabh or grah (if it be written thus: see 729 a) contracts to gṛh, making the three forms of stem jagráh (1st and 2d sing. act.), jagrā́h (3d), and jagṛh; but prach (if it be so written: see 756 a) remains unchanged throughout.
d. Some roots omit in weak forms of this tense, or in some of them, a nasal which is found in its strong forms: thus, we have cakradé etc. (RV.) from √krand; tatasré (RV.) from √taṅs; dadaçvā́ṅs (RV.) from √daṅç; bedhús, bedhé, etc. (AV.) from √bandh; sejus (ÇB.) from √sañj; caskabhāná (AV.) from √skambh; tastabhús etc. (V.), tastabhāná (V.B.), from √stambh. Compare also 788 a.
e. A number of roots having medial a between single consonants drop that vowel. These are, in the later language, gam, khan, jan,
