The Sandhi That Split the Revision Class
In a Sunday revision batch of 32 Madhyama candidates, the teacher writes three sandhi items on the board: (1) रामः + अस्ति, (2) नर + इन्द्रः, and (3) तत् + हितम्. The class is told that the internal test awards one mark for the combined form and one mark for naming the operation. Two students, Asha and Manoj, disagree. Asha writes रामोऽस्ति, नरेन्द्रः, तद्धितम्. Manoj writes रामोअस्ति, नरैन्द्रः, तद्हितम्, arguing that the sounds must remain visible and that ऐ is the vṛddhi of अ + इ. A third student asks whether a form that is understandable but not rule-generated should receive full marks. The teacher has ten minutes, a printed answer key that gives only the final forms, and no time to consult a grammar. You are asked to settle the three items and advise on marking.
1. For each of the three items, state the correct combined form and the operation that produces it. Show how you would convince Manoj rather than merely correcting him.

Correct forms:
- रामः + अस्ति → रामोऽस्ति. The visarga after अ is replaced by ओ before the voiced vowel अ, and the following अ is elided; the avagraha in रामोऽस्ति marks that elision. Writing रामोअस्ति leaves two vowels in hiatus and is not the sandhi form.
- नर + इन्द्रः → नरेन्द्रः. The final अ of नर and initial इ of इन्द्र combine to ए, the guṇa grade. Manoj's नरैन्द्रः uses vṛddhi, which is not the grade required by this compound and produces a non-standard form.
- तत् + हितम् → तद्धितम्. The final त् of तत् becomes द् before ह्, and ह् becomes ध्; the result is written with द्ध. तद्हितम् fails to show the assimilation of ह्.
To convince Manoj, show the sound changes step by step and ask him to pronounce each intermediate form; the impossible cluster is audible. Then let him apply the same steps to a new item so that he sees the rule working, not just the answer.
2. Manoj asks: if a listener understands रामोअस्ति, why should the school test penalize it? Write the reasoning you would give about acceptability, not just correctness.

Understanding is not the same as grammatical acceptability. रामोअस्ति may be guessed, but it violates a compulsory sandhi and obscures the boundary between words; the examiner is testing whether the candidate can apply the operation, not whether a reader can reconstruct the meaning. In a one-mark form plus one-mark rule scheme, the form mark depends on the sandhi and the rule mark on naming it. A form that is understandable but ungenerated should not receive full marks because it does not demonstrate the skill being assessed. The fair response is to award partial credit only if the intended form is clear, and to require the correct form for full credit.
3. Design one parallel set of three items that tests the same three operations without repeating the forms, and give the expected answers with brief reasons.

Parallel set:
(a) बालः + अपि → बालोऽपि. Same visarga operation: visarga becomes ओ before अ, and the following अ is elided. (b) गज + आननः → गजाननः. अ + आ combine to आ; this tests vowel combination rather than consonant assimilation. (c) सत् + जनः → सज्जनः. The final त् assimilates before ज्, giving ज्ज; this tests the consonant operation.
The set is parallel because each item isolates a different operation while keeping the same marking logic: one mark for the form, one for the operation. It does not repeat the original words, so students must transfer the rule.
