Sandhi or Samāsa? Diagnosing a Class's Compound-Splitting Errors
In a Class 10 Telugu revision session at a government school in Lucknow, 34 students take a 10-mark grammar slip test. Item 3 asks them to split 'రామాలయము' and name the sandhi; item 4 asks them to split 'రాజకుమారుడు' and name the samāsa. Twenty-two scripts write 'రామ + ఆలయము' but label it గుణ సంధి. Seventeen label 'రాజకుమారుడు' as ద్వంద్వ and gloss it 'రాజు మరియు కుమారుడు'. Only nine correctly write షష్ఠీ తత్పురుష with the meaning 'రాజు యొక్క కుమారుడు'. The textbook glossary lists both terms but does not contrast them. The teacher has one 40-minute period before the board model test, only the chalkboard and the marked scripts, and no time to print a new worksheet. Most students can recite the sandhi formulae but freeze when they must choose between a sandhi label and a samāsa label for the same surface string.
1. State the correct analysis for both test items and give a decision rule that separates sandhi from samāsa for these forms.

రామాలయము: the split is రామ + ఆలయము. The first member ends in అ and the second begins with ఆ; both belong to the same vowel class (అ/ఆ), so the rule is సవర్ణదీర్ఘ సంధి (అ/ఆ + అ/ఆ → ఆ). It is not గుణ సంధి: గుణ gives ఏ, ఓ or అర్ when అ/ఆ meets ఇ/ఈ, ఉ/ఊ or ఋ. The 22 scripts remembered the vowel change but attached the wrong label.
రాజకుమారుడు: the split is రాజు + కుమారుడు. The meaning is 'రాజు యొక్క కుమారుడు' (the king's son), so the first member stands in the genitive relation and the compound is షష్ఠీ తత్పురుష. It is not ద్వంద్వ: a ద్వంద్వ needs co-ordinate members that can be joined by 'మరియు' and normally refers to both together ('రాజు మరియు కుమారుడు'). Here only the son is meant.
Decision rule: (1) split the word and state its meaning; (2) if the change is only a vowel/consonant junction inside a single word, label the sandhi; (3) if two nominal stems are combined into one noun, label the samāsa and test the relation with 'యొక్క' (tatpurusha), 'మరియు' (dvandva), or a qualifying adjective (karmadharaya).
2. Design a 10-minute chalkboard drill using the marked scripts, and explain how it addresses the two error clusters.

Put two columns on the board: సంధి and సమాసం. In the first column write a minimal pair: రామ + ఆలయము → రామాలయము, and మహా + ఋషి → మహర్షి. Ask two students to mark the first vowel and the second vowel, then say why the first is సవర్ణదీర్ఘ and the second is గుణ. This directly attacks the 22 scripts that knew 'ఆ + ఆ' but not the governing vowel-class rule.
In the second column write రాజు + కుమారుడు and రామ + లక్ష్మణులు. Ask students to insert 'యొక్క' or 'మరియు' between the members. Only the form that takes 'యొక్క' and names one person is షష్ఠీ తత్పురుష; the form that takes 'మరియు' and names both is ద్వంద్వ. This attacks the 17 scripts that translated with 'మరియు' without testing the meaning.
Make students justify the label in one sentence, not just write it. Award the mark for the justification. In 10 minutes the class completes four examples and sees that the label follows the meaning test, not the surface string.
