Rule. The affixes taught before the sūtra dikśabdebhyaḥ… (SK 1974) are given the name (saṃjñā) vibhakti. The same word already names the case-endings. Now it also names these taddhitas.
Example.
bahubhyaḥ "from many" → the affix tasil (SK 1953), which is a vibhakti by this rule
→ bahutaḥ "from many".
The plain form bahubhyaḥ remains correct beside it.
Applies when / blocked by. The sūtra says "before diś". One of Bhaṭṭoji's commentators says this means the sūtra that contains that word. That is why Bhaṭṭoji writes "before dikśabdebhyaḥ".
Bhaṭṭoji adds three remarks. First, "now the svārthika affixes". A svārthika affix comes in the base's own sense: it adds no meaning of its own. Second, two words of SK 1072 stop running here: samarthānām and prathamāt. Third, vā "optionally" does continue. So each derived form stands beside the inflected word.
One of Bhaṭṭoji's commentators gives three purposes for the name vibhakti. It brings in the prohibition of SK 190. It brings in tyadādy-atva (SK 265), which needs a vibhakti after it. And it brings in an accent rule, SK 3717, taught in the accent chapter. The same commentator says the continuation of vā rests on the received interpretation alone.
Watch out. Is this a naming rule or a heading? The editor of the printed edition says it is a naming rule, known from the received interpretation. Otherwise it could be read as a heading, like prāk kaḍārāt.
Our text writes atha svārthikā pratyayāḥ, with the ḥ of svārthikāḥ lost. The 1915 printed edition reads svārthikāḥ, and this book follows the print.
The affixes (pratyaya) to be taught before [the sūtra] 'dikśabdebhyaḥ …' (SK 1974) are to bear the designation (saṃjñā) vibhakti. Now [follow] affixes in the base's own sense (svārthika). [The words] 'samarthānām' and 'prathamāt' [of 'samarthānāṃ prathamād vā', SK 1072] have ceased [to run] (nivṛtta); 'vā', however, does continue (anuvartate).
- commentary BM: by the word 'diś' the sūtra that contains that word is meant; hence Bhaṭṭoji's 'dikśabdebhya ity ataḥ'. Followed for the bracketed reference in sutra_en and k1.
- commentary BM: the purpose of the vibhakti designation is the prohibition 'na vibhaktau tusmāḥ' (SK 190), the substitution of a for tyad etc. (tyadādy-atva, SK 265), and the accent taught by 'ūḍidampadādi…' (SK 3717). 'svārthikāḥ' means 'arising in the sense of their own base (prakṛti)', because no sense is specified for tasil and the rest, and expressions such as 'atiśāyane' qualify the sense of the base. On 'nivṛttam': the reasoning was given under 'samarthānām' (SK 1072). On 'anuvartata eva': explanation (vyākhyāna) alone is the authority here. Followed for 'in the base's own sense'.
- textual NSP editorial footnote 2, p. 318 (printed 308), marked at 'vibhaktisaṃjñāḥ' (scan): that this is a saṃjñā-sūtra is to be known from the explanation (vyākhyāna) of the sūtra; otherwise it could also be taken as an adhikāra, like 'prāk kaḍārāt'. Recorded. The footnote is not filed in any source.json. Footnote 3 on the same page ('adhikriyate') belongs to SK 1948.
- textual Our source reads 'atha svārthikā pratyayāḥ'; NSP p. 318 (printed 308) reads 'atha svārthikāḥ pratyayāḥ' (scan confirms). The English follows the print; the visarga has dropped in the digital text.
- translator No Tattvabodhinī comment on this sūtra exists in our source or in the print. TB (NSP p. 318) passes directly from 'iti matvarthīyāḥ', the end of sk.1933.t1, to 'kiṃsarvanāma—' (SK 1948), which was printed at the tail of sk.1933.t1 and re-filed to sk.1948.t1 (2026-10-05).
