Kc 28

[Kaccāyanabyākaraṇaṃ, Sandhikappa, Tatiyakaṇḍa, Sutta 28]

28. 40. Paradvebhāvo ṭhāne (67).

Saramhā parassa byañjanassa dvebhāvo hoti ṭhāne.

In some places, after a vowel, there is doubling of the following consonant.

Idha ppamādo, purisassa jantuno, pabbajjaṃ kittayissāmi (Khu. i, 340),
cātuddasiṃ (A. i, 142), pañcaddasiṃ (A. i, 142), abhikkantataro cando.

Examples:

idhappamādo: idha pamādo; idha ppamādo (28); idhappamādo (11).

purisassa. Here there is the insertion of ‘s’ after the stem ‘purisa’ before
the inflection ‘sa’ (fourth and sixth inflection masculine singular). See
§61.

pabbajjaṃ: pa bajjaṃ; pa bbajjaṃ (28); pabbajjaṃ (11).

cātuddasiṃ: cātu dasiṃ; cātu ddasiṃ (28); cātuddasiṃ (11).

pañcaddasiṃ: pañca dasiṃ; pañcaddasiṃ (28); pañcaddasiṃ (11).

abhikkantataro: abhi kantataro; abhi kkantataro (28); abhikkantataro (11).

Ṭhāne ti kasmā? Idha modati pecca modati (Khu. i, 15).

Why say ‘in some places’? To prevent the operation of this rule in the
following: Idha modati pecca modati.

Counter Examples:

idha modati pecca modati. Here there is no doubling of ‘m’ after ‘a’ of idha
and pecca.
