Etymology

The word "inadvertently" traces back to Latin roots. The prefix "in-" negates the following morpheme, while "advert" derives from the Latin "advertere" (to turn toward, notice). The suffix "-ent" forms adjectives, and "-ly" converts it into an adverb. Over time, the sense of "not turning attention" evolved into "unintentionally."
