flagitious
"shamefully wicked, criminal," late 14c., from O.Fr. flagicieux or directly from L. flagitiosus "shameful, disgraceful, infamous," from flagitium "shameful act, passionate deed, disgraceful thing," related to flagrum "a whip, scourge, lash," flagitare "to demand importunately," from PIE root *bhlag- "to strike." Related: Flagitiously; flagitiousness.
flagrant
c.1500, "resplendent," from L. flagrantem (nom. flagrans) "burning, blazing, glowing," figuratively "glowing with passion, eager, vehement," prp. of flagrare "to burn, blaze, glow" from L. root *flag-, corresponding to PIE *bhleg- "to shine, flash, burn" (cf. Gk. phlegein "to burn, scorch," L. fulgere "to shine"), from root *bhel- (1) "to shine, flash, burn" (see bleach). Sense of "glaringly offensive" first recorded 1706, probably from common legalese phrase in flagrante delicto "red-handed," lit. "with the crime still blazing." Related: Flagrantly.
