If you trace the etymology of "disavow" back through Middle English to Anglo-French, you'll arrive eventually at the prefix "des-" and the verb "avouer," meaning "to avow." The prefix "des-" in turn derives from the Latin prefix "dis-," meaning "apart." That Latin prefix plays a significant role in many current English words, including "disadvantage," "disappoint," and "disagree." "Avouer" is from Latin "advocare," meaning "to summon," and is also the source of our word "advocate."
