Today we will look at the word “धिय:” from the गायत्री-मन्त्र: – “धियो यो न: प्रचोदयात्“

धी gets प्रातिपदिकसंज्ञा by 1-2-45 अर्थवदधातुरप्रत्‍ययः प्रातिपदिकम्.  प्रत्ययाः सुँ, औ, जस् etc. are mandated by

4-1-2 स्वौजसमौट्छष्टाभ्याम्भिस्ङेभ्याम्भ्यस्ङसिँभ्याम्भ्यस्ङसोसाम्ङ्योस्सुप्. The विवक्षा here is द्वितीया विभक्तिः बहुवचनम् so we begin with

1. धी + शस्

2. धी+ अस् । 1-3-8 लशक्वतद्धिते gives इत्संज्ञा to श् and 1-3-9 तस्य लोपः causes it to disappear. 1-3-4 न विभक्तौ तुस्माः prevents the स् in शस् from getting इत्संज्ञा

3. धियँङ्+ अस् । 6-4-77 अचि श्नुधातुभ्रुवां य्वोरियङुवङौ gives इयँङ् as आदेशः to धी. By 1-1-53 ङिच्च this आदेशः applies to the last अल् in धी, i.e. to ईकारः

4. धिय् + अस् । अँ gets इत्संज्ञा by 1-3-2 उपदेशेऽजनुनासिक इत् and ङ् gets इत्संज्ञा by 1-3-3 हलन्त्यम् and both disappear by 1-3-9 तस्य लोपः

5. धियः Applying रुँत्व-विसर्गौ (8-2-66 ससजुषो रुँ, 8-3-15 खरवसानयोर्विसर्जनीयः)

Questions:

1. Which rule would have applied after step 2 if 6-4-77 were not there? What would have been the (undesired) form?

2. Why did 6-4-82 एरनेकाचोऽसंयोगपूर्वस्य not apply in step 3? Which required condition(s) was/were not satisfied?

3. Among the 24 forms in the declension table of the प्रातिपदिकम् “धी” how many are the form “धिय:”?

4.  The ending ईकार: of the term “धी” comes from a धातु: (Otherwise we couldn’t have used 6-4-77)  Which धातु: is it?

5.  The प्रातिपदिकम् in the word “यो” is “यद्”  Though we have not yet discussed consonant-ending stems, we have covered all the rules required to derive this form.  Can you show the derivation?
