masc nom sg of samudaya (noun)
Analysis. saṁ + ud + aya: 'coming together upward', the rising together of conditions. In the Four Noble Truths, samudayo denotes the arising of dukkha through the convergence of causes and conditions.
Etymology. saṁ (together) + ud (up, out) + √i (go): literally 'going up together'. The prefix saṁ brings things into one; ud adds the sense of upward emergence or arising. Cognate with English 'out' (ud-) and Greek eu- in its spatial sense of outward movement. The compound imagery—multiple streams converging and rising—captures how dependent origination (paṭiccasamuppāda) works: conditions arise together.
