शुभगो इति रूपे ‘भाग्यवान्’ इत्यर्थः; स्न्वादिगणप्रत्यययुक्ते तु ‘तत्कर्ता’ इति कर्तृवाचकः। प्रोक्तशब्दोऽन्यस्थानगतश्चेत् तस्यैव भावस्य क्षयविनाशं बोधयति।

It teaches that meaning is not fixed merely by a word’s surface form; context and grammatical formation determine sense—an important discipline for correctly understanding dharma and moksha teachings.
Indirectly: it safeguards bhakti and moksha teachings by insisting on precise interpretation—misreading terms can distort doctrines about devotion, merit, and liberation.
Vedanga Vyākaraṇa/Nirukta: the verse illustrates how affixes (like those in the snvādi group) and syntactic placement shift a term from ‘possessing fortune’ to ‘causing/producing an effect,’ or even to a sense of loss/diminution.
