masc nom sg of dayāpanna (adj)
Analysis. dayā (compassion, kindness) + panna (accomplished, skilled) — one accomplished in kindness; the stem dayā is the absolutive of dāti 'gives' and carries the sense of giving/generosity that underlies compassion.
Etymology. dayā derives from √dā 'give' (cognate with Latin dō, English donation, Sanskrit dadāti), with the prefix da- intensifying the root into an abstract noun for the virtue of giving and thus compassion. Panna is the past participle of pa-√jñā 'know distinctly', so the compound literally pictures one who 'knows compassion well' or 'is skilled in compassion'.
