masc nom sg of taṇhākkhaya (noun)
Analysis. taṇhā (craving, thirst) + kkhaya (wearing away, decay); a key doctrinal compound denoting the cessation of tanhā as the goal of the path—nirvana understood as the final decay of the fuel that feeds saṃsāra.
Etymology. taṇhā derives from √tṛṣ (Sanskrit tṛṣ) 'to thirst'—cognate with English thirst, German Durst, and Latin torrēre 'to parch'; kkhaya is the Pali form of Sanskrit kṣaya, from √kṣi 'to decay, wear away', cognate with English consume and Latin caedere 'to fell, cut'. The compound captures a central Buddhist insight: craving as the active thirst that must literally be worn away.
