accusative singular masculine of upakkilesa (noun)
Analysis. upa- (near, alongside) + kilesa (defilement, corruption) — a defilement that approaches or clings close to the practice, less gross than major defilements but still obstructing clarity.
Etymology. From upa- (near, intimate) and kilesa (mental afflictions, corruption), cognate with Sanskrit kilbiṣa (guilt, transgression). The prefix upa- keeps its sense of close-up proximity: minor defilements that lurk near the threshold of awareness.
