dissemble

We don't have anything to hide: "dissemble" is a synonym of "disguise," "cloak," and "mask." "Disguise" implies a change in appearance or behavior that misleads by presenting a different apparent identity. "Cloak" suggests a means of hiding a movement or an intention. "Mask" suggests some often obvious means of hiding or disguising something. "Dissemble" (from Latin dissimulare, meaning "to hide or conceal") stresses the intent to deceive, especially about one's own thoughts or feelings, and often implies that the deception is something that would warrant censure if discovered.
