Origin of disconcert
From the obsolete French word disconcerter, dating back to 1680–90. See dis- 1, concert
Explanation
To disconcert is to unsettle someone, or make them feel confused and out of sorts. Finding a soup ladle in your sock drawer would definitely disconcert you! Disconcert comes from the old French word disconcerter, meaning "confused." The prefix dis means "not" — it has a bad attitude and shows up in words like disagree and disown. The second part of the word comes from the verb concerter, "to bring together." If you disconcert someone, you make them feel uncomfortable and maybe a little embarrassed.
