In the history of language study, a number of signposts can be erected to mark the path. The simplest outline consists of two major parts: a prescientific and a scientific period. The first can be dispensed with in short order.
The earliest formal grammar of any language is a detailed analysis of classical Sanskrit, written by the Indian scholar Pnini in the fourth century b.c.e. He called it the Sutras (instructions), and in it, he codified the rules for the use of proper Sanskrit. It is still an authoritative work. Independently of Pnini, the ancient Greeks established many grammatical concepts that strongly influenced linguistic thinking for hundreds of years. Platonic realism, although by today’s standards severely misguided in many respects, offered a number of useful insights into language, among them the basic division of the sentence into subject and predicate, the recognition of word stress, and the twofold classification of sounds into consonants and vowels. In the third century b.c.e., Aristotle defined the various parts of speech. In the next century, Dionysius Thrax produced a grammar that not only improved understanding of the sound system of Greek but also classified even more clearly the basic parts of speech and commented at length on such properties of language as gender, number, case, mood, voice, tense, and person. At no time, though, did the Hindu and Greek scholars break away from a focus on their own language to make a comparison with other languages. This fault was also largely one of the Romans, who merely adapted Greek scholarship to their own needs. If they did any comparing of languages, it was not of the languages in the Roman world, but only of Latin as a “corrupt” descendant of Greek. In sum, the Romans introduced no new concepts; they were, instead, content to synthesize or reorganize their legacy from ancient Greece. Only two grammarians come to mind from the fourth and fifth centuries of the Roman Empire—Priscian and Donatus, whose works served for centuries as basic texts for the teaching of Latin.
The scientific period of language study began with a British Sanskrit scholar, Sir William Jones, who headed a society organized in Calcutta for the exploration of Asia. In 1786, he delivered a paper in which he stated thatthe Sanskrit language . . . [was] more perfect than the Greek, more copious than the Latin, and more exquisitely refined than either; yet [bore] to both of them a stronger affinity . . . than could possibly have been produced by accident; so strong, indeed, that no philologer could examine them all three without believing them to have sprung from some common source, which, perhaps, no longer exists.
He went on to say that Germanic and Celtic probably had the same origin. His revolutionary assertion that Sanskrit and most of the languages of Europe had descended from a single language no longer spoken and never recorded first...
