Etymology
Origin of conceal
First recorded in 1275–1325; Middle English conselen, concelen, from Anglo-French conceler from Latin concēlāre, from con- con- + cēlāre “to hide” ( see also hull 1)
Explanation
When you conceal something, you are keeping it from being discovered: “To avoid another argument with his cousins, Jonathan worked hard to conceal his disappointment at the outcome of the race.” The verb conceal can be used to describe the hiding of feelings (as in “to conceal anger”) or facts (as in “to conceal identity”). Conceal also can be used to describe the act of hiding or covering an item to prevent discovery. If you eat the last piece of chocolate cake, for example, you may want to conceal the evidence by removing the icing-stained plate from your room.
