सर्वसमासान्तप्रकरणम्

Covers SK 940–957 (18 sūtras), Aṣṭādhyāyī 5.4.74–85 (the samāsāntas common to every compound type: the affix a after ṛc/pur/ap/dhur/pathin and the affix ac after a closed list of stems) with the two uttarapada rules 6.3.97–98 spliced in for ap, and the prohibitions 5.4.69–72 placed last. All numbers present.

sarvasamāsānta-prakaraṇa — outline (p23, SK 940–957, all 18 sūtras)

The samāsāntas common to all compounds (sarvasamāsānta): under the heading samāsāntāḥ (SK 676, 5.4.68) and the taddhita adhikāra, two affixes are added as the final member (antāvayava) of a compound regardless of its type — the bare a after a compound ending in ṛc, pur, ap, dhur, pathin (940), and ac (a with c-marker for accent) after a fixed list of final members or of whole ready-made forms (943–953). Both are taddhitas, so a stem-final n loses its ṭi by nas taddhite (6.4.144) — pathin → path-a, loman → lom-a — and where the nipātana wants a ṭi-lopa the rule would not give (aṣṭhīvat, tāvatī), the sūtra simply sets it down. The chapter closes with the prohibitions that limit these affixes — after a word of honour (su/ati), after censuring kim, after nañ in a tatpuruṣa — and the one option (pathin after nañ). Only the kaumudī blocks are translated; the commentators' settled readings (Bālamanoramā, Tattvabodhinī) are drawn on for vigrahas and steps. Ordering: SK order except that (i) 942's dhur/pathin examples are read back into group A (they exemplify 940, not 942), (ii) 953 upasargād adhvanaḥ is placed with the other "ac after a named final member" rules in E, and (iii) 944 akṣṇo 'darśanāt is paired with 952 dvistāvā tristāvā vediḥ in F as the two sense-restricted cases.

A. The samāsānta a after ṛc / pur / ap / dhur / pathin — running example: ṛco 'rdham → ardharca-a → ardharcaḥ (also viṣṇoḥ pūḥ → viṣṇupuram, rājño dhūḥ → rājadhurā, sakhyuḥ panthāḥ → sakhipathaḥ)

B. The ī / ū substitutes on ap once it carries the samāsānta — running example: dvir gatā āpo yasmin → dvi + ap + a → dvi + īp-a → dvīpam (also anu + ap + a → anūpo deśaḥ)

C. ac after sāman / loman with prati-anu-ava, and the yogavibhāga extensions (bhūmi, nadī, godāvarī, padmanābha) — running example: pratigataṃ sāma → prati-sāman + ac → pratisāmam (also anugataṃ loma → anulomam)

D. The twenty-five ready-made ac forms of the acatura-list — running example: avidyamānāni catvāry asya → a-catur + ac → acaturaḥ (bahuvrīhi only)

E. ac after a named final member — varcas / tamas / vasīyas-śreyas / rahas / uras / adhvan — and the nipātana anugavam — running example: brahmaṇo varcaḥ → brahma-varcas + ac → brahmavarcasam (also pragato 'dhvānam → prādhvo rathaḥ)

F. The two sense-restricted cases — akṣi not as "eye", dvistāvā / tristāvā only of the vedi — running example: gavām akṣīva → gava-akṣi + ac → gavākṣaḥ (also dvis tāvatī → dvistāvā vediḥ)

G. Where the samāsāntas are barred, and the one option — honour-words, censuring kim, nañ-tatpuruṣa, pathin — running example: su + rājan → surājā (no ṭac); na panthāḥ → apatham / apanthāḥ
