The word "inadequately" combines the negative prefix "in-" (from Latin, meaning "not") with "adequate" (from Latin "adaequatus," meaning "made equal" or "sufficient"). The suffix "-ly" (from Old English "-lice") converts the adjective into an adverb. The term evolved to describe actions or states that fall short of what is required or expected, emphasizing insufficiency.
