f. Examples of other formations occurring in the older language are as follows: root-infinitive, -sthāpam, -vāsas; — infinitive in tu, other cases than accusative, -janayitave; jánayitavāí, pā́yayitavāí, -çcotayitavāí; çámayitos; — infinitive in dhyāi, iṣayádhyāi, īrayádhyāi, taṅsayádhyāi, nāçayádhyāi, mandayádhyāi, mādayádhyāi, riṣayádhyāi, vartayádhyāi, vājayádhyāi, syandayádhyāi (all RV.); — gerundive in āyya, panayā́yya, spṛhayā́yya, trayayā́yya (? √trā).
g. Other noun-derivatives from the causative stem are not infrequent, being decidedly more numerous and various than from any other of the secondary conjugation-stems. Examples (of other kinds than those instanced in 1044) are: árpaṇa, dāpana, prīṇana, bhī́ṣaṇa; jñāpaka, ropaka; patayālú, spṛhayālu; jánayati, jñapti.
h. All the classes of derivatives, it will be noticed, follow in regard to accent the analogy of similar formations from the simple root, and show no influence of the special accent of the causative-stem.
1052. Derivative or Tertiary Conjugations. From the causative stem are made a passive and a desiderative conjugation. Thus:
a. The passive-stem is formed by adding the usual passive-sign य yá to the causatively strengthened root, the causative-sign being dropped: thus, धार्यते dhāryáte.
b. Such passives are hardly found in the Veda (only bhājyá- AV.), but some thirty instances are met with in the Brāhmaṇas and Sūtras: examples are jñapyá- (TS.), sādya- (K.), pādya- (AB.), vādya- (TB.), sthāpya- (GB.); and they become quite common later.
c. The desiderative stem is made by reduplication and addition of the sign इष iṣa, of which the initial vowel replaces the final of the causative stem: thus, दिधारयिषति dídhārayiṣati.
d. These, too, are found here and there in the Brāhmaṇas and later (about forty stems are quotable): examples are pipāyayiṣa (K.), bibhāvayiṣa and cikalpayiṣa and lulobhayiṣa (AB.), dídrāpayiṣa and rirādhayiṣa and āpipayiṣa (ÇB.), and so on.
e. As to causatives made from the intensive and desiderative stems, see above, 1025, 1039.
V. Denominative.
1058. A denominative conjugation is one that has for its basis a noun-stem.
a. It is a view now prevailingly held that most of the present-systems of the Sanskrit verb, along with other formations analogous with a
