for the problematic vanuṣanta of RV.), which are also regular. Bhaviṣāt (AB. once) is a solitary example of a form with double mode-sign; cániṣṭhat (RV.; SV. instead jániṣṭhat) seems hopelessly corrupt. The radical syllable always has the accent, and its vowel usually accords with that of the indicative: but we have san- in the subjunctive against asāniṣam (as to cay- and ran-, see below, 908).
907. The middle optative of this aorist also forms a part of the accepted "precative" of the later language (923, 925 b). It is very rare at all periods, being made in RV. from only five roots, and in AV. from two of the same and from three additional ones (six of the eight have other iṣ-forms); and the remaining texts add, so far as noticed, only four other roots. All the forms found to occur are as follows: janiṣīya, indhiṣīya, edhiṣīyá, ruciṣīya and rociṣīya, gmiṣīya; modiṣīṣṭhās; janiṣīṣṭa; vaniṣīṣṭa; sahiṣīvahi; idhiṣīmahi, edhiṣīmáhi, janiṣīmahi, tāriṣīmahi, mandiṣīmahi, vandiṣīmáhi, vardhiṣīmáhi, sahiṣīmahi and sāhiṣīmáhi. The accent is on the ending, and this would lead us to expect a weak form of root throughout; but the usage in this respect appears to be various, and the cases are too few to allow of setting up any rule. The forms janiṣeyam and -ya, from a secondary a-stem, occur in K.
908. Of imperative forms, we have from √av a series: namely, aviḍḍhí, aviṣṭu, aviṣṭám, avitá (if this, as seems probable, stands anomalously for aviṣṭá) and aviṣṭána; two of these are of unmistakably imperative form. Other forms occur only in 2d du. and 2d pl., and are accordingly such as might also be subjunctives used imperatively (which is further made probable for two of them by their accentuation on the root-syllable): they are kramiṣṭam, gamiṣṭam, caniṣṭám, cayiṣṭam (against acāyiṣam), tā́riṣṭam, yodhiṣṭam, vadhiṣṭam, çnathiṣṭam; ráṇiṣṭana (against arāṇiṣus), çnathiṣṭana.
909. No words having a participial ending after iṣ are found anywhere to occur.
910. This is the only aorist of which forms are made in the secondary and denominative conjugations: see below, 1035, 1048, 1068.
6. The siṣ-aorist.
911. According to the grammarians, this aorist is made from roots in आ ā (including मि mi fix, मि mi (or mī) damage and ली lī cling, which substitute forms in ā), and from नम् nam bow, यम् yam reach, and रम् ram be content, and is used only in the active; the corresponding middle being of the s-form (878 ff.). Its inflection is precisely like that of the iṣ-aorist; it is unnecessary, then, to give more than
