Remarks.
(a) Sometimes the gerund having been formed by means of ya, the ya is dropped, the root
alone remaining, as in;
abhiññā, having known, = abhiññāya.
paṭisaɲkhā, having pondered, = paṭisaɲkhāya.
anupādā, not having clung, not clinging, = anupādāya (an + upa + ā + √dā + ya).
(b) Some roots seem to take a compound gerundial suffix, made up of ya and tvā, and
joined to the root by means of i, as:
āruyhitvā ( √ruh), having ascended.
ogayhitvā ( √gāh = gah), having dived = ogayha = ogāhitvā.
(c) There are some anomalous forms:
disvā, from √dis to see = having seen.
daṭṭhu = disvā.
anuvicca, from √vid, to know = having known, final d being dropped before tya.
pappuyya, from √āp + pa = pāp, to obtain = pāpayitvā.
vineyya. from √nī, having removed.
niccheyya, from √ni = having ascertained.
In these last three examples the y has undergone reduplication.
atisitvā, from √sar = Sanskrit sṛ.(?), having approached, having excelled.
