Today we will look at the form प्रवरान्तरम्  nAs from श्रीमद्भागवतम् 9.16.37

एष वः कुशिका वीरो देवरातस्तमन्वित । अन्ये चाष्टकहारीतजयक्रतुमदादयः ।। ९-१६-३६ ।।
एवं कौशिकगोत्रं तु विश्वामित्रैः पृथग्विधम् । प्रवरान्तरमापन्नं तद्धि चैवं प्रकल्पितम् ।। ९-१६-३७ ।।

श्रीधर-स्वामि-टीका
हे कुशिकाः, एष देवरातो वो युष्मदीयः कौशिक एव । यतो वीरो मत्पुत्रस्तमेनमन्वितानुगच्छत । अन्ये चाष्टकादयस्तस्य सुता आसन् ।। ३६ ।। उपसंहरति – एवमिति । एके शप्ता एकेऽनुगृहीता अन्यस्तु पुत्रत्वेन स्वीकृत इत्येवं कौशिकगोत्रं पृथग्विधं नानाप्रकारं जातं तच्च प्रवरान्तरमापन्नं प्राप्तम् । हि यस्मादेवं देवरातज्येष्ठत्वेन तत्प्रकल्पितम् ।। ३७ ।।

Gita Press translation – “This valiant Devarāta is one of you (as good a scion of Kuśika as you), O scions of Kuśika! (Hence) follow him (as an elder brother).” There were other sons too of Viśwāmitra – Aṣṭaka, Hārīta, Jaya, Kratumān and so on (36). Thus, of course, the line of Kuśika was ramified into various off-shoots due to the sons of Viśwāmitra. And it acquired a different Pravara (branch name, viz., that of Devarāta) inasmuch as it was given a new shape (with Devarāta as the eldest son of Viśwāmitra) (37).

(1) अन्यः प्रवरः = प्रवरान्तरम् – different Pravara (branch name.)

(2) प्रवर सुँ + अन्तर सुँ । As per 2-1-72 मयूरव्यंसकादयश्च – ‘मयूरव्यंसक’ etc are given as ready-made तत्पुरुषः compounds.
Note: अविहितलक्षणस्तत्पुरुषो मयूरव्यंसकादिषु द्रष्टव्य: – A तत्पुरुषः compound that is accepted in usage but is not prescribed by any rule should be considered to be part of the मयूरव्यंसकादि-गण:। Hence even though the तत्पुरुषः compound प्रवरान्तरम् is not specifically listed in the मयूरव्यंसकादिगण: we may consider it to be included therein.
Note: ‘अन्तर’ is used in the sense of ‘अन्य’ (another)/ ‘भिन्न’ (different) here and it has been placed in the latter position in the compound even though it is the adjective. The सूत्रम् 2-1-72 मयूरव्यंसकादयश्च is necessary to justify this compound because if we were to use the सूत्रम् 2-1-57 विशेषणं विशेष्येण बहुलम्‌ the विशेषणम् (adjective) ‘अन्तर’ would have to be placed in the prior position in the compound.
Note: ‘प्रवर सुँ + अन्तर सुँ’ gets the designation प्रातिपदिकम्‌ by 1-2-46 कृत्तद्धितसमासाश्च। This allows 2-4-71 to apply in the next step.

(3) प्रवर + अन्तर । By 2-4-71 सुपो धातुप्रातिपदिकयोः – A सुँप् affix takes a लुक् elision when it is a part of a धातुः or a प्रातिपदिकम्।

(4) प्रवरान्तर । By 6-1-101 अकः सवर्णे दीर्घः।

Note: Even though ‘प्रवर’ is masculine, the compound ‘प्रवरान्तर’ is used in the neuter gender because that is how it is (considered to be ) listed in the मयूरव्यंसकादिगण:। It declines like वन-शब्द:।

The विवक्षा is द्वितीया-एकवचनम्।

(5) प्रवरान्तर + अम् । By 4-1-2 स्वौजसमौट्छष्टाभ्याम्भिस्ङेभ्याम्भ्यस्ङसिभ्याम्भ्यस्ङसोसाम्ङ्योस्सुप्‌।

(6) प्रवरान्तर + अम् । By 7-1-24 अतोऽम् – The affixes ‘सुँ’ and ‘अम्’ that follow a neuter अङ्गम् ending in the short vowel ‘अ’ take ‘अम्’ as their replacement. 1-3-4 न विभक्तौ तुस्माः prevents the ending letter ‘म्’ of the affix ‘अम्’ from getting इत्-सञ्ज्ञा।
Note: 7-1-24 is required here to prevent 7-1-23 स्वमोर्नपुंसकात्‌ from applying.

(7) प्रवरान्तरम् । By 6-1-107 अमि पूर्वः – In place of a preceding अक् letter and the following vowel (अच्) belonging to the affix ‘अम्’ there is a single substitute of that preceding अक् letter.
