accusative singular masculine of kiṁsamudaya (compound noun)
Analysis. kiṁ (what, interrogative/indefinite) + samudaya (arising, origin; from sam- 'together' + ud- 'up' + aya 'going', hence 'coming-together upward'). The compound treats kiṁ as an indefinite: 'that which arises together', used specifically for dukkha-samudaya, the origin of suffering—the Second Noble Truth taught by the Buddha.
Etymology. Samudaya derives from sam- (together, completely) + ud- (up, out) + √i (go), giving 'arising, origin'. The prefix sam- condenses multiple causes into one emergent phenomenon; ud- conveys the upward, outward manifestation. Compare English 'up' and 'out', and Sanskrit sam-UT-thita 'risen up together'. In Buddhist doctrine, kiṁsamudaya is the standard Pali rendering of dukkha-samudaya, the cause and origin of suffering.
