flagrantly

The adverb 'flagrantly' is built upon the adjective 'flagrant', which originates from the Latin verb flagrare, meaning 'to burn, blaze, or be on fire'. This literal sense of burning evolved metaphorically in Late Latin to describe a crime that was 'blazing' or 'glaring' in its obviousness and offensiveness, much like a fire is impossible to ignore. The English adjective adopted this figurative meaning of 'conspicuously wicked', and the standard adverbial suffix '-ly' was appended to form 'flagrantly', describing an action done in a manner that is shockingly and openly evident, as if illuminated by flames.

Structure: flagrant (blazing, obvious) + ly (adverb suffix) - flagrant: From Latin flagrant- (stem of flagrans), present participle of flagrare meaning 'to burn, blaze'. It functions as the core adjective meaning 'blazing, glaringly bad'. - ly: From Old English -līce, an adverbial suffix forming adverbs from adjectives, indicating manner.
