Today we will look at the form द्यावाभूम्योः fGd from श्रीमद्भागवतम् 5.20.43.

अण्डमध्यगतः सूर्यो द्यावाभूम्योर्यदन्तरम् । सूर्याण्डगोलयोर्मध्ये कोट्यः स्युः पञ्चविंशतिः ।। ५-२०-४३ ।।
मृतेऽण्ड एष एतस्मिन्यदभूत्ततो मार्तण्ड इति व्यपदेशः । हिरण्यगर्भ इति यद्धिरण्याण्डसमुद्भवः ।। ५-२०-४४ ।।

श्रीधर-स्वामि-टीका
विस्तरेणोक्तं ब्रह्माण्डमानं सर्वतोऽपि निरूपयति । अण्डमध्यगतः । किं तन्मध्यं तदाह । द्यावाभूम्योः पूर्वोत्तरकपालयोर्यदन्तरं मध्यस्थानम् । सर्वतः पञ्चविंशतिकोट्यः ।। ४३ ।। अण्डमध्यावस्थाने कारणं तन्नामनिर्वचनेनाह । मृतेऽचेतने एष सूर्यो वैराजरूपेण यस्मात्प्रविष्टः ।। ४५ ।।

Gita Press translation – (The orb of) the sun is located in the middle of the egg (of this universe), which corresponds to the center of space lying between heaven (the upper shell of the cosmic egg) and earth (the lower shell of the cosmic egg.) The (extent of) space between (the orb of) the sun and (the outer shell of) the cosmic egg (on all sides) is twenty-five crore Yojanas (or two thousand million miles) (43). Because the sun-god appeared in this lifeless (inanimate) egg (as the Cosmic Being), the appellation of Mārtaṇḍa (मृते अण्डे भवः) has been applied to him (ever) since. He is (also) called Hiraṇyagarbha inasmuch as he (as the sun) represents the embryo (located) in (the centre of) the golden egg (of this universe) (44).

(1) द्यौश्च भूमिश्च = द्यावाभूमी – Heaven and earth.

(2) दिव् सुँ + भूमि सुँ । By 2-2-29 चार्थे द्वन्द्वः – Two or more terms having the designation पदम् and standing in a relation expressible by ‘च’ (‘and’) may optionally compound to yield a compound called द्वन्द्वः।

(3) दिव् सुँ + भूमि सुँ । Note: ‘दिव्’ has one syllable while ‘भूमि’ has two syllables. Therefore ‘दिव्’ is placed in the prior position in this द्वन्द्व: compound as per 2-2-34 अल्पाच्तरम्‌ – In a द्वन्द्व: compound the term having the least number of syllables (vowels) is placed in the prior position.

Note: ‘दिव् सुँ + भूमि सुँ’ gets the designation प्रातिपदिकम्‌ by 1-2-46 कृत्तद्धितसमासाश्च। This allows 2-4-71 to apply in the next step.

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

(5) द्यावाभूमि । By 6-3-29 दिवो द्यावा – When the final member of the compound follows, in a द्वन्द्व: compound whose terms denote names of deities there is a substitution of ‘द्यावा’ in the place of the term ‘दिव्’। As per 1-1-55 अनेकाल्शित्सर्वस्य, the entire term ‘दिव्’ is replaced by ‘द्यावा’।

As per the सूत्रम् 2-4-26 परवल्लिङ्गं द्वन्द्वतत्पुरुषयोः, the compound प्रातिपदिकम् ‘द्यावाभूमि’ is feminine since the final member ‘भूमि’ of the compound is feminine. This द्वन्द्वः compound (which expresses इतरेतरयोगः) is dual in number because it has two members. It declines like मति-शब्द:।

The विवक्षा is षष्ठी।

(6) द्यावाभूमि + ओस् । By 4-1-2 स्वौजसमौट्छष्टाभ्याम्भिस्ङेभ्याम्भ्यस्ङसिभ्याम्भ्यस्ङसोसाम्ङ्योस्सुप्‌। 1-3-4 न विभक्तौ तुस्माः prevents the ending letter ‘स्’ of ‘ओस्’ from getting the इत्-सञ्ज्ञा।

(7) द्यावाभूम्योस् । By 6-1-77 इको यणचि।

(8) द्यावाभूम्यो: । रुँत्व-विसर्गौ – 8-2-66 ससजुषो रुः and 8-3-15 खरवसानयोर्विसर्जनीयः।
