Successor of Sakatayana

Nirukta
Vedanga on etymology
A commentary on Nighantu, a compilation of rare or difficult words
The Nighanu and Nirukta are typically treated as one document.
Three parts:
Naighantuka kanda - a collection of synonyms in three adhyayas
Physical things and nature
Man, qualities associated with man
Abstract qualities and concepts
Naigama kanda - a collection of words found only in the Vedas
Daivata kanda - a collection of names for deities
Ideas
Four main categories of words
Nama - nouns
Akhyata - verbs
Upasarga - prefixes
Nipata - particles
Two main ontological categories of speech
Words became nouns or verbs depnding on which feature was predominant.
Process or action (bhava)
Entity or being (sattva)
Nominal forms result in a 'petrified' verb (murta)
Words are the primary carriers of meaning
This is as opposed to sentences being the primary carriers of meaning, which is the Paninian position
The debate in which this is a position is between Nairuktas and Vaiyakaranas
It is part of the larger debate regarding compositionality between Mimamsakas and Vaiyakaranas
Gargya, of the opposiing side, argues for example that prepositions have various senses of their own even when detached, where Sakatayana argues that they only contribute to word-meanings and have no sense in themselves.
The Nairukta's position is exposited in Sakatayana's sutra:
samhita pada-prakrtih
