In a flagrant manner; obviously, outrageously, or brazenly wrong in a way that is impossible to deny or ignore.
From 'flagrant' (from Latin 'flagrare,' to burn) plus the adverb suffix '-ly' (from Old English '-lice,' meaning in the manner of). The '-ly' suffix converts adjectives into adverbs.
When someone acts 'flagrantly' wrong, they're not just doing something bad—they're doing it so obviously and openly that they might as well be waving a burning torch, which is exactly what the Latin root suggests!
