न प्राच्यभर्गादियौधेयादिभ्यः

The तद्राजा affix is not elided in the feminine, if it forms the names of the क्षत्रिय-sūtras of the East or it comes after the word भर्ग etc. and यौधेय etc.
This sutra debars the elision of the Tadraja affix अ (required by the last sutra). Thus पांचाली, वैदेही, आंगी, वांगी, मागधी these being all Eastern people dwelling in countries east of the Sarasvati river. Similarly of भर्ग &c. Thus भार्गी, कारुषी, कैकेयी ॥ So also of यौधेय &c. Thus यौधेयी, शौभ्रेयी and शौक्रेयी ॥ The Tadraja affixes taught above are five, but besides these there are others taught in the fifth Adhyaya 5.3.112 to 5.3.119. The word यौधेय is formed by such an affix (5.3.177 अञ्). The present rule, therefore indicates by implication, that the rule of elision contained in 4.1.177 applies not only to the Tadraja affixes taught in this chapter, but to the Tadraja affixes taught in 5.3.112 to 5.3.119. Thus the Tadraja affix अण् in 5.3.117 added to पशु &c. is elided in the feminine: e.g. m. पार्शवः, f. पर्शू, m आसुरः f असुरी--&c.
