In a way that is well-known or famous; noticeably or strikingly.
From Middle English 'famous,' derived from Old French 'fameus,' from Latin 'famosus' (well-known). The adverb form adds '-ly' to create an adverbial modifier.
The word 'famous' comes from the Latin 'fama' (rumor/report), which is also the root of 'defame'—meaning fame and infamy originally came from the same concept of what people are saying about you.
