c. RV. has the stems ínakṣa and íyakṣa, regarded as desideratives from √√naç attain and yaj, with mutilated reduplication.
1030. A number of roots, including some of very common use, form an abbreviated stem apparently by a contraction of reduplication and root together into one syllable: thus, ईप्स īpsa from √आप् āp; दित्स ditsa from √दा dā.
a. Such abbreviated stems are found in the older language as follows: dhitsa (beside didhiṣa) from √dhā; ditsa (beside didāsa) from √dā; dipsa (dhīpsa JB.) from √dabh; çikṣa from √çak; sīkṣa from √sah: these are found in RV.; in AV. are added īpsa from √āp (RV. has apsa once), and īrtsa from √ṛdh; the other texts furnish lipsa (ÇB.) or līpsa (TB.) from √labh, ripsa (GB.) from √rabh, pitsa (ÇB.) from √pad, and dhīkṣa (ÇB.) from √dah (not √dih, since no roots with i as medial vowel show the contracted form). In the later language are further found pitsa from √pat also, jñīpsa from the causative quasi-root jñap (below, 1042 j), and the anomalous mitsa from √mā measure (allowed also from roots mi and mī); and the grammarians give ritsa from √rādh. Also mokṣa is (very questionably) viewed as a desiderative stem from √muc.
1031. The use of the auxiliary vowel इ i is quite rare in the early language, but more common later; and it is allowed or prescribed by the grammarians in many stems which have not been found in actual use.
a. It is declared to follow in general, though not without exceptions, necessary or optional, the analogy of the futures (934, 943 a).
b. No example of the use of i is found in RV., and only one each in AV. (pipatiṣa), VS. (jijīviṣa), and TS. (jigamiṣa). The other examples noted in the early texts are açiçiṣa, cikramiṣa, jigrahīṣa (with ī for i, as elsewhere in this root), cicariṣa, edidhiṣa, jijaniṣa, didīkṣiṣa, bibādhiṣa, ruruciṣa, vivadiṣa, vividiṣa, çiçāsiṣa, tiṣṭighiṣa, jihiṅsiṣa: most of them are found only in ÇB. Stems also without the auxiliary vowel are made from roots gam, grah, car, jīv, pat, bādh, vid.
1032. Inflection: Present-System. The desiderative stem is conjugated in the present-system with perfect regularity, like other a-stems (733 a), in both voices, in all the modes (including, in the older language, the subjunctive), and with participles and imperfect. It will be sufficient to give here the first persons only. We may take
