तद्धिताश्चाप्यपत्यार्थे पांडवाः श्रैधरस्तथा । गार्ग्यो नाडायनात्रेयौ गांगेयः पैतृष्वस्रीयः ॥ ५१ ॥
taddhitāścāpyapatyārthe pāṃḍavāḥ śraidharastathā | gārgyo nāḍāyanātreyau gāṃgeyaḥ paitṛṣvasrīyaḥ || 51 ||
तद्धिताः प्रत्यया अप्यपत्यार्थे प्रयुज्यन्ते; ततो ‘पाण्डवाः’ ‘श्रैधरः’ इत्यादयः। तथा ‘गार्ग्यः’ ‘नाडायन’ ‘आत्रेयौ’ ‘गाङ्गेयः’ ‘पैतृष्वस्रीयः’ इति रूपाणि जायन्ते॥

It highlights Vedāṅga Vyākaraṇa as a support-discipline for Dharma and Mokṣa: correct derivation and usage of lineage/kinship terms preserves the integrity of tradition, recitation, and teaching.
Indirectly: Bhakti practices rely on faithful transmission of names, lineages, and teachings; grammar (Vyākaraṇa) safeguards the meaning of sacred words that devotees recite and hear.
Vyākaraṇa (grammar), specifically taddhita-pratyayas used in apatyārtha—forming patronymics and kinship-based words such as Gārgya, Ātreya, and Gāṅgeya.
