accusative singular masculine of saṅkilesa (noun)
Analysis. saṁ + kilesa: 'bringing together' (saṁ-) defiling things (kilesa), hence a collective defilement or corruption that clouds the mind.
Etymology. saṁ (together) + kilesa (defilement, from √klis 'to trouble, afflict'). The prefix saṁ- intensifies kilesa from individual defilements to their accumulated, binding force in the mind. Cognate with Greek klyzo 'to wash, drench' (opposite sense), and English 'clean'.
