masculine noun, accusative singular
Analysis. paṭi- (back, against) + a- (toward) + √kī (make, do, become): the thing that 'comes back toward' or 'counters' an effect as its condition.
Etymology. The prefix paṭi- (back, against) with ā (toward) and the root kī (make, do): literally 'counter-acting'; the concrete image of one thing leaning back against another to support or condition it shapes the abstract sense of causality. In Pali metaphysics (paṭiccasamuppāda, dependent co-arising), paccaya denotes the conditions without which an effect cannot arise.
