Kc 24

[Kaccāyanabyākaraṇaṃ, Sandhikappa, Tatiyakaṇḍa, Sutta 24]

24. 35. Sare kvaci (63).

Sarā kho sare pare kvaci pakatirūpāni honti.

When a vowel follows, vowels sometimes retain their original forms.

Ko imaṃ pathaviṃ vicessati (Khu. i, 19).

Examples:
ko imaṃ. Here the ‘o’ of ko remains unchanged when followed by a
vowel.

Kvacī ti kasmā? Appassut' āyaṃ puriso (khu. i, 36).

Why say ‘sometimes’? To prevent the operation of this rule in the
following: Appassut' āyaṃ puriso.

Counter Examples:
appassutāyaṃ: appassuto ayaṃ; appassut o ayaṃ (10); appassut  ayaṃ
(12); appassut āyaṃ (15); appassutāyaṃ (11).
