mistakenly
UK: /mɪˈsteɪ.kən.li/ | US: /mɪˈsteɪ.kən.li/
adv. in a way that is incorrect or based on a misunderstanding
adv. by error; unintentionally
The word "mistakenly" derives from the verb "mistake" (Old Norse mistaka, "take wrongly"), combined with the suffix "-en" (used to form past participles or adjectives, as in "broken") and the adverbial suffix "-ly" (from Old English -līce). The progression reflects a logical shift: from the act of making an error ("mistake") to the state of being wrong ("mistaken"), and finally to the manner of acting ("mistakenly").
