masc nom sg of khīṇāsava (adj)
Analysis. khīṇa (pp of khaṇati, destroyed) + āsava (effluent, corruption): one in whom the āsavas (taints of sensuality, existence, ignorance, and views) have been burned away or exhausted, leaving only the cool lucidity of arahatship.
Etymology. khīṇa derives from √khaṇ (to dig, dig away), cognate with Sanskrit kṣaṇ- and ultimately Indo-European √sken- (to cut, scrape); āsava from √su (to flow) with prefix ā- (toward), literally "that which flows toward" — the inflowing contaminants. The compound epitomizes the destructive path of the Dhamma: one must dig out (khīṇa) the root defilements that have flowed in (āsava).
