Nirukta, Phonetic Variants, and Vedic Dhātu–Svara Taxonomy
सनाद्यंता धातवश्च तथा वै नामधातवः । एवमानंत्यमुद्भाव्यं धातूनामिह नारद । संक्षेपोऽयं समुद्दिष्टो विस्तरस्तत्र तत्र च ॥ ७६ ॥
sanādyaṃtā dhātavaśca tathā vai nāmadhātavaḥ | evamānaṃtyamudbhāvyaṃ dhātūnāmiha nārada | saṃkṣepo'yaṃ samuddiṣṭo vistarastatra tatra ca || 76 ||
So werden auch die Verbalwurzeln erfasst, die die sanādi-Affixe annehmen, ebenso die sogenannten nāmadhātu (denominativen Wurzeln). Auf diese Weise, o Nārada, wird hier die Weite und nahezu endlose Spannbreite der Wurzeln angedeutet. Dies ist die knappe Darlegung; die ausführliche Erklärung findet sich an den jeweiligen Stellen.

Indirectly: by emphasizing correct linguistic foundations (dhātu, pratyaya, nāmadhātu), it supports accurate recitation and understanding of mantras and scriptures—key supports for steady Vishnu-bhakti and scriptural listening (śravaṇa).
Vyākaraṇa: the classification of dhātus, including sanādi-derived forms and nāmadhātus, and the method of teaching—first a saṃkṣepa (summary), then vistaras (detailed treatment) in the proper grammatical contexts.
