Pāṇini cites at least ten grammarians and linguists before him. According to Sumitra Mangesh Katre, the ten Vedic scholar names he quotes are of Apisali, Kashyapa, Gargya, Galava, Cakravarmana, Bharadvaja, Sakatayana, Sakalya, Senaka and Sphotayana.[11]
Determining the exact century of Yaska is difficult, and opinions of different scholars vary from 7th–5th century BC.[1] Pāṇini mentions Yaska as one of the previous linguists, and so Yaska must precede Pāṇini.[citation needed]
The Nirukta attempts to explain how certain words get to have their meanings, especially in the context of interpreting the Vedic texts. It includes a system of rules for forming words from roots and affixes, and a glossary of irregular words, and formed the basis for later lexicons and dictionaries. It consists of three parts, viz.: (i) Naighantuka, a collection of synonyms; (ii) Naigama, a collection of words peculiar to the Vedas, and (iii) Daivata, words relating to deities and sacrifices.
Nirukta, or etymology was one of the six vedangas or compulsory subjects in the syllabus of Vedic scholarship in ancient India.
Yāska singled out two main ontological categories: a process or an action (bhāva), and an entity or a being or a thing (sattva). Then he first defined the verb as that in which the bhāva ('process') is predominant whereas a noun is that in which the sattva ('thing') is predominant. The 'process' is one that has, according to one interpretation, an early stage and a later stage and when such a 'process' is the dominant sense, a finite verb is used as in vrajati, 'walks', or pacati, 'cooks'.[13]
But this characterisation of noun / verb is inadequate, as some processes may also have nominal forms. For e.g., He went for a walk. Hence, Yāska proposed that when a process is referred to as a 'petrified' or 'configured' mass (mūrta) extending from start to finish, a verbal noun should be used, e.g. vrajyā, a walk, or pakti, a cooking. The latter may be viewed as a case of summary scanning,[14]
since the element of sequence in the process is lacking.
As in modern semantic theory, Yāska views words as the main carriers of meaning. This view – that words have a primary or preferred ontological status in defining meaning, was fiercely debated in the Indian tradition over many centuries. The two sides of the debate may be called the Nairuktas (based on Yāska's Nirukta, atomists), vs the Vaiyākarans (grammarians following Pāṇini, holists), and the debate continued in various forms for twelve centuries involving different philosophers from the Nyaya, Mimamsa and Buddhist schools.
In the prātishākhya texts that precede Yāska, and possibly Sakatayana as well, the gist of the controversy was stated cryptically in sutra form as "saṃhitā pada-prakṛtiḥ". According to the atomist view, the words would be the primary elements (prakṛti) out of which the sentence is constructed, while the holistic view considers the sentence as the primary entity, originally given in its context of utterance, and the words are arrived at only through analysis and abstraction.
This debate relates to the atomistic vs holistic interpretation of linguistic fragments – a very similar debate is raging today between traditional semantics and cognitive linguistics, over the view whether words in themselves have semantic interpretations that can be composed to form larger strings. The cognitive linguistics view of semantics is that any definition of a word ultimately constrains its meanings because the actual meaning of a word can only be construed by considering a large number of individual contextual cues.
Yāska also defends the view, presented first in the lost text of Sakatayana that etymologically, most nouns have their origins in verbs. An example in English may be the noun origin, derived from the Latin originalis, which is ultimately based on the verb oriri, "to rise". This view is related to the position that in defining agent categories, behaviours are ontologically primary to, say, appearance. This was also a source for considerable debate for several centuries (see Sakatayana for details).
