The word "undid" is derived from the Old English word "undon" or "undon" (past participle of "undǣn"), which itself is a combination of the prefix "un-" and the verb "do". The prefix "un-" is used to express the reverse or opposite of an action, while "do" means to perform or carry out. In this case, "undid" is the past tense form of the verb "undo".
