By the same or a very similar process denominative verbs are formed in Sanskrit to a very large extent. From +râjan+, king, we form +râjâ-ya-te+, he behaves like a king, literally, he goes the king, he acts the king, _il a l’allure d’un roi_. From +kumârî+, girl, +kûmârâ-ya-te+, he behaves like a girl, etc.[15] After raising +naś+ to +nâśa+, and adding the same radical +ya+, Sanskrit produces a causative verb, +nâśa-ya-ti+, he sends to destruction, the Latin _nêcare_. In close analogy to the neuter verb +naśyati+, the regular passive is formed in Sanskrit by composition with +ya+, but by adding, at the same time, a different set of personal terminations. Thus +náś-yá-ti+ means he perishes, while +naś-yá-te+ means he is destroyed. The usual terminations of the Optative in Sanskrit are:-- yâm, yâs, yât, yâma, yâta, yus, or, after bases ending in vowels:-- iyam, is, it, ima, ita, iyus. In Greek:-- ιην, ιης, ιη, ιημεν, ιητε, ιεν, or, after bases ending in o:-- ιμι, ις, ι, ιμεν, ιτε, ιεν. In Latin:-- iêm iês iet ---- ---- ient, îm, îs, it, îmus, îtis, int. If we add these terminations to the root +AS+, to be, we get the Sanskrit +s-yâm+ for +as-yâm+:-- syâm, syâs, syât, syâma, syâta, syus. Greek ἐσ-ίην, contracted to εἴην:-- εἴην, εἴης, εἴη, εἴημεν, εἴητε, εἶεν Latin _es-iem_, changed to _siêm_, _sîm_, and _erîm_:-- siêm, siês, siet,[16] ---- ---- sient. sim, sîs, sit,[17] sîmus, sitis, sint. erîm, erîs, erit, erîmus, erîtis, erint. If we add the other termination to a verbal base ending in certain vowels, we get the Sanskrit +bhara-iyam+, contracted to +bháreyam+:-- bharêyam, bharês, bharêt, bharêma, bharêta, bharêyus. in Greek φέρο-ιμι:-- φέρο-ιμι, φέρο-ις, φέρο-ι, φέρο-ιμεν, φέρο-ιτε, φέρο-ιεν in Latin _fere-im_, changed to _ferem_, used in the sense of a future, but replaced[18] in the first person by _feram_, the subjunctive of the present:-- feram, ferês, feret, ferêmus, ferêtis, ferent. Perfect Subjunctive:-- tul-erîm, tul-erîs, tul-erit, tul-erimus, tul-eritis,[19] tul-erint. Here we have clearly the same auxiliary verb, i or +ya+, again, and we are driven to admit that what we now call an optative or potential mood, was originally a kind of future, formed by +ya+, to go, very much like the French _je vais dire_, I am going to say, I shall say, or like the Zulu 1 2 3 4 1 2 3 4 +ngi-ya-ku-tanda+, I go to love, I shall love.[20] The future would afterwards assume the character of a civil command, as “thou wilt go” may be used even by us in the sense of “go;” and the imperative would dwindle away into a potential, as we may say: “Go and you will see,” in the same sense as, If you go, you will see. The terminations of the future are:-- Sanskrit:-- syâmi, syasi, syati, syâmas, syâtha, syanti. Greek:-- σω, σεις, σει, σομεν, σετε, σοντι.
