Grammatical Analysis
Samudaya: [m.] origin; source; cause; arising; coming together. Formed by prefix saṃ (together) + ud (up) + root i (to go). Literally means “going or rising up together,” implying a combination of factors that simultaneously produce a result.
Orthodox Definition
In the fundamental layout of the Four Noble Truths, Samudaya constitutes the Second Noble Truth: the origin or cause of suffering (dukkha-samudaya). The Buddha explicitly isolated craving (taṇhā) as the primary operational force within this truth.
The Mahāvihāra commentary explains that while craving is singled out due to its prominent role in pulling consciousness into renewed existence, Samudaya structurally encompasses all unwholesome volitions and mental defilements (kilesa) that sustain the wheel of Dependent Origination.
As a functional requirement of the path, the Truth of Origin must be completely abandoned (pahātabba). One does not suppress the results (suffering); one cuts the specific, active causal root (craving).
