The ancient Indian language, like the literature composed in it, falls into the two main divisions of Vedic and Sanskrit. The former differs from the latter on the whole about as much as Homeric from classical Greek, or the Latin of the Salic hymns from that of Varro. Within the Vedic language, in which the sacred literature of India is written, several stages can be distinguished. In its transitions from one to the other it gradually grows more modern till it is ultimately merged in Sanskrit. Even in its earliest phase Vedic cannot be regarded as a popular tongue, but is rather an artificially archaic dialect, handed down from one generation to the other within the class of priestly singers. Of this the language itself supplies several indications. One of them is the employment side by side of forms belonging to different linguistic periods, a practice in which, however, the Vedic does not go so far as the Homeric dialect. The spoken language of the Vedic priests probably differed from this dialect of the hymns only in the absence of poetical constructions and archaisms. There was, in fact, even in the earlier Vedic age, a caste language, such as is to be found more or less wherever a literature has grown up; but in India it has been more strongly marked than in any other country. If, however, Vedic was no longer a natural tongue, but was already the scholastic dialect of a class, how much truer is this of the language of the later literature! Sanskrit differs from Vedic, but not in conformity with the natural development which appears in living languages. The phonetic condition of Sanskrit remains almost exactly the same as that of the earliest Vedic. In the matter of grammatical forms, too, the language shows itself to be almost stationary; for hardly any new formations or inflexions have made their appearance. Yet even from a grammatical point of view the later language has become very different from the earlier. This change was therefore brought about, not by new creations, but by successive losses. The most notable of these were the disappearance of the subjunctive mood and the reduction of a dozen infinitives to a single one. In declension the change consisted chiefly in the dropping of a number of synonymous by-forms. It is probable that the spoken Vedic, more modern and less complex than that of the hymns, to some extent affected the later literary language in the direction of simplification. But the changes in the language were mainly due to the regulating efforts of the grammarians, which were more powerful in India than anywhere else, owing to the early and exceptional development of grammatical studies in that country. Their influence alone can explain the elaborate nature of the phonetic combinations (called Sandhi) between the finals and initials of words in the Sanskrit sentence.
