645. According to all the analogies of the first general conjugation, we should expect to find the accent upon the root-syllable when this is strengthened. That is actually the case, however, only in a small minority of the roots composing the class: namely, in hu, bhī (no test-forms in the older language), hrī (no test-forms found in the older language), mad (very rare), jan (no forms of this class found to occur) , ci notice (in V.), yu separate (in older language only), and in bhṛ in the later language (in V. it goes with the majority: but RV. has bibhárti once, and AV. twice; and this, the later accentuation, is found also in the Brāhmaṇas); and RV. has once iyárṣi. In all the rest — apparently, by a recent transfer — it rests upon the reduplicating instead of upon the radical syllable. And in both classes alike, the accent is anomalously thrown back upon the reduplication in those weak forms of which the ending begins with a vowel; while in the other weak forms it is upon the ending (but compare 666 a).
a. Apparently (the cases with written accent are too few to determine the point satisfactorily) the middle optative endings, īya etc. (566), are reckoned throughout as endings with initial vowel, and throw back the accent upon the reduplication.
646. The verbs of this class lose the न् n in the 3d pl. endings in active as well as middle, and in the imperfect have उस् us instead of अन् an — and before this a final radical vowel has guṇa.
647. The combination of stem and endings is as in the preceding class.
Examples of inflection: a. √हु hu sacrifice: strong stem-form, जुहो juhó; weak form,जुहु juhu (or júhu).
