Sphoṭa

Sphoṭa (Sanskrit: स्फोट, IPA: [ˈspʰoːʈɐ]; "bursting, opening", "spurt") is an important concept in the Indian grammatical tradition of Vyakarana, relating to the problem of speech production, how the mind orders linguistic units into coherent discourse and meaning.

It is used in its technical linguistic sense by Patañjali (2nd century BCE), in reference to the "bursting forth" of meaning or idea on the mind as language is uttered.

The acoustic element (dhvani) can be long or short, loud or soft, but the sphoṭa remains unaffected by individual speaker differences.

[2] Eternal qualities in language are already postulated by Yāska, in his Nirukta (1.1), where reference is made to another ancient grammarian, Audumbarāyaṇa, about whose work nothing is known, but who has been suggested as the original source of the concept.

[3] The grammarian Vyāḍi, author of the lost text Saṃgraha, may have developed some ideas in sphoṭa theory; in particular some distinctions relevant to dhvani are referred to by Bhartṛhari.

[4] There is no use of sphoṭa as a technical term prior to Patañjali, but Pāṇini (6.1.123) refers to a grammarian named Sphoṭāyana as one of his predecessors.

[2] Bhartṛhari develops this doctrine in a metaphysical setting, where he views sphoṭa as the language capability of man, revealing his consciousness.

The sphoṭa is the causal root, the intention, behind an utterance, in which sense is similar to the notion of lemma in most psycholinguistic theories of speech production.

Bimal K. Matilal (1990) has tried to unify these views - he feels that for Bhartṛhari the very process of thinking involves vibrations, so that thought has some sound-like properties.

Sphoṭa theory remained widely influential in Indian philosophy of language and was the focus of much debate over several centuries.

Adherents of the 'sphota' doctrine were holistic or non-compositional (a-khanḍa-pakṣa), suggesting that many larger units of language are understood as a whole, whereas the Mīmāṃsakas in particular proposed compositionality (khanḍa-pakṣa).

The position was most ably stated by Kumarila Bhatta (7th century) who argued that the 'sphoṭas' at the word and sentence level are after all composed of the smaller units, and cannot be different from their combination.
