1037. Verbal Nouns and Adjectives. These too are made with the auxiliary vowel इ i, in all cases where that vowel is ever taken.
a. In the older language have been noted: participle in ta, mīmāṅsitá (AV., GB.), jijyūṣita (AB.), çuçrūṣitá and dhīkṣitá (ÇB.); — gerundive in tavya, līpsitavya (AB.), didhyāsitavyà (ÇB.); in ya, jijñāsyà (ÇB.); — gerund in tvā, mīmāṅsitvā (K.).
1038. Of other declinable stems derived from the desiderative stem, by far the most common are the adjective in ú — e. g. titikṣu, dipsú, bībhatsú, siṣāsú (RV. once didṛ́kṣu) — and the abstract noun in ā́ — e. g. īpsā, bībhatsā́, mīmāṅsā́, çuçrūṣā — both of which are made with increasing freedom from an early epoch of the language: especially the former, which has the value and construction (271 a) of a present participle. A few adjectives in enya (having a gerundive character: 966 b) occur in the earlier language: thus, didṛkṣéṇya (RV.), çuçrūṣéṇya (TS.), ninīṣeṇya (PB.), jijñāsenya (AB.), and, with irregular reduplication (apparently) papṛkṣéṇya (RV.), dadhiṣeṇya (JB.); and didṛkṣéya (RV.) is a similar formation. RV. has also siṣāsáni and rurukṣáṇi, and siṣāsátu (?). In the later language, besides some of the formations already instanced (those in u and ā, and in sya and sitavya), are found a few derivatives in aka, as cikitsaka, bubhūṣaka; in ana, as jijñāsana, didhyāsana; and, very rarely, in anīya (cikitsanīya) and tṛ (çuçrūṣitṛ); further, secondary derivatives (doubtless) in in from the noun in ā, as īpsin, jigīṣin (one or two of these occur in the older language). And of an adjective in a we have an example in bībhatsá (B.S., and later), and perhaps in avalipsa (AVP.); such words as ajugupsa, duçcikitsa, are rather to be understood as possessive compounds with the noun in ā. As to noun-stems in is, see 392 d.
1039. Derivative or Tertiary Conjugations. A passive is allowed to be made, by adding the passive-sign य yá to the desiderative root (or stem without final a): thus, ईप्स्यते īpsyáte it is desired to be obtained; — and a causative, by adding in like manner the causative-sign अय áya (1041): thus, ईप्सयामि īpsáyāmi I cause to desire obtainment.
a. Of these formations in the older language are found mīmāṅsyámāna (doubtless to be read for -sámāna, AV.), lipsyámāna (ÇB.), and rurutsyamāna (K.). Half-a-dozen such passives are quotable later, and one or two causatives: e. g. cikitsyate, vivakṣyate, jijñāsyate; cikīrṣayant, cikitsayiṣyati.
b. For the desiderative conjugation formed on causative stems, which is found as early as the Brāhmaṇas, see below, 1052 b.
