the word 'unwisely' is a layered construction built upon the core germanic adjective 'wise.' the old english wīs conveyed the sense of having knowledge and good judgment, a concept deeply rooted in proto-germanic \wīsaz. the prefix 'un-', also from old english, is a prolific negator, directly reversing the adjective's meaning to 'not wise.' finally, the adverbial suffix '-ly,' evolving from old english -līce (meaning "having the body or form of"), was attached to create the manner adverb. thus, the literal morphemic sequence "not" + "wise" + "in the manner of" logically coalesces into the modern sense of acting in a way that lacks wisdom or prudence.
