Kc 41

[Kaccāyanabyākaraṇaṃ, Sandhikappa, Catutthakaṇḍa, Sutta 41]

41. 56. Byañjano ca visaññogo (135-6, 149).

Niggahitamhā parasmiṃ sare lutte yadi byañjano sasaññogo visaññogo hoti.

When the vowel that follows the niggahita is elided, if the syllable has a
conjunct consonant, it becomes [a] single consonant.

Evaṃ 'sa te āsavā (M. i, 13), pupphaṃ 'sā uppajji (Vin. i, 21).

Examples:
evaṃsa: evaṃ assa; evaṃ ssa (40); evaṃ sa (41); evaṃsa.
pupphaṃsā: pupphaṃ assā; pupphaṃ ssā (40); pupphaṃ sā (41); pupphaṃsā.

Lutte ti kasmā? Evam assa (Vin. i, 265) vidhūn' aggam iti.

Why say ‘elided’? To prevent the operation of this rule in the following:
Evam assa vidhūn' aggam iti.

Counter Examples:
evamassa: evaṃ assa. Here there is no elision of the vowel that follows the
     niggahita.
vidhūnaggam: vidhūnaṃ aggaṃ. Since there is no elision of the ‘a’ of aggaṃ,
     the conjunct consonant ‘gg’ does not become [a] single consonant.

Caggahaṇena tiṇṇaṃ byañjanānam antare ye sarūpā, tesam pi lopo hoti.
Agyāgāraṃ (Vin. ī, 145); paṭisanthāravuty assa (Khu. i, 67).

By taking ‘ca’, when there are three consonants, there is also elsion of
those consonants that are similar.

Examples:
agyāgāraṃ: aggi āgāraṃ; aggy āgāraṃ (21); agy āgāraṃ (41); agyāgāraṃ.
paṭisanthāravutyassa: paṭisanthāravutti assa; paṭisanthāravutty assa (21);
     paṭisanthāravuty assa (41); paṭisanthāravutyassa.
