pr 3rd sg of pasīdati (verb)
Analysis. pa + √sid, 'settles forward': the prefix pa- (forth, forward) intensifies the root √sid (settle, sink), shifting from physical subsidence to clarity of mind and emotional ease.
Etymology. √sid (settle, sink down) + pa- prefix. The root √sid is cognate with Latin sīdō (settle, sink), and the prefix pa- (forward, forth) works intensively here, as in pajānāti. The concrete image of sediment settling (clarity emerging from turbidity) underlies the meanings of mental clarity and calm.
