a. The forms with primary endings are: in active, stoṣāṇi; darṣasi; neṣati, parṣati, pāsati, matsati, yoṣati, vakṣati, sakṣati; dā́sathas, dhāsathas, párṣathas, vakṣathas, varṣathas; pāsatas, yaṁsatas, yakṣatas, vakṣatas; dhāsatha, neṣatha, párṣatha, mátsatha; — in middle, naṁsāi, máṅsāi; máṅsase; kraṁsate, trāsate, darṣate, máṅsate, yakṣate, rāsate, vaṅsate, sākṣate, hāsate; trā́sāthe (not trāsāithe, as we should rather expect); náṁsante, máṅsante: and, with the fuller ending in 3d sing., mā́sātāi.
b. The forms with secondary endings are (active only): jéṣas, vákṣas; dárṣat, néṣat, pákṣat, párṣat, préṣat, yákṣat, yóṣat, váṅsat, vákṣat, véṣat, sátsat, chantsat, etc. (some twenty others); yakṣatām; váṅsāma, sā́kṣāma, stoṣāma; parṣan, yaṁsan, yoṣan, rā́san, vakṣan, çéṣan, çróṣan. Of these, yakṣat and vakṣat are found not rarely in the Brāhmaṇas; any others, hardly more than sporadically.
894. Of irregularities are to be noted the following:
a. The forms dṛ́kṣase and pṛkṣase (2d sing. mid.) lack the guṇa-strengthening.
b. Jeṣam, stoṣam, and yoṣam (AV. yūṣam, with ū for o as in anūṣata etc.) appear to be first persons formed under government of the analogy of the second and third — unless they are relics of a state of things anterior to the vṛddhi-strengthening: in which case jeṣma is to be compared with them (we should expect jāiṣma or jeṣāma).
c. From roots in ā are made a few forms of problematic character: namely, yeṣam (only case in RV.), khyeṣam, jñeṣam, geṣam and geṣma, deṣma, seṣam and set, stheṣam and stheṣus. Their value is optative. The analogy of jeṣam and jeṣma suggests the possibility of their derivation from i-forms of the ā-roots; or the sibilant might be of a precative character (thus, yā-ī-s-am). That they really belong to the iṣ-aorist appears highly improbable.
d. The RV. has a few difficult first persons middle in se, which are perhaps best noted here. They are: 1. from the simple root, kṛṣe, hiṣe (and ohiṣe?), stuṣé; 2. from present-stems, arcase, ṛñjase, yajase, gāyiṣe, gṛṇīṣé and punīṣé. They have the value of indicative present. Compare below, 897 b.
895. Optative forms of this aorist are made in the middle only, and they have in 2d and 3d sing. always the precative s before the endings. Those found to occur in the older language are: diṣīya, dhiṣīya, bhakṣīyá, masīya (for maṅsīya), mukṣīya, rāsīya, lopsīya, sākṣīya, stṛṣīya; maṅsīṣṭhās; darṣīṣṭa, bhakṣīṣṭa, maṅsīṣṭa, mṛkṣīṣṭa; bhakṣīmahi, dhukṣīmáhi, maṅsīmáhi, vaṅsīmáhi, vasīmahi, sakṣīmáhi; maṅsīrata. PB. has bhukṣiṣīya, which should belong to a siṣ-aorist. The RV. form trā́sīthām (for trāsīyāthām or trāsāthām) is an isolated anomaly.
a. This optative makes a part of the accepted "precative" of the later language: see below, 923, 925 b.
