peccant

Origin

The adjective is borrowed from Middle French peccant (“unhealthy”) (modern French peccant), and from its etymon Late Latin peccantis, the genitive singular of peccāns (“offending; sinning, transgressing”, adjective), from Latin peccāns (“wrongdoer”), a noun use of the active present participle of peccō (“to offend; to sin, transgress”), ultimately from Proto-Indo-European *ped- (“to fall; to stumble; to step; to walk”). As regards adjective sense 3 (“diseased, unhealthy”) as used in peccant humours, compare Middle French l'umeur peccante, humeurs peccantes, Old French humeurs pechantes, and Late Latin humores peccantes. The noun is derived from the adjective.
