nominative singular masculine of vītataṇha (adjective), with vocative particle āvuso; surface form shows sandhi contraction
Analysis. vīta- (gone, departed) + taṇha (thirst, craving); āvuso is a vocative particle (friend, sir) appended in direct address. The genitive -ssa- bridges the nominative adjective with the vocative particle in Pali's colloquial contraction of address formulas.
Etymology. vīta is the past participle of vi + eti (vi 'apart' + eti 'goes', meaning 'has gone away'); taṇha (thirst) is cognate with Sanskrit tṛṣṇā and ultimately Indo-European *terə- (to cross, to parch). The compound reflects the Buddha's teaching that cessation of craving marks liberation.
