What does unmask mean?
Unmask is a verb meaning to remove a mask or disguise, or to reveal something that has been concealed. Its figurative uses are especially common: an investigation may unmask a criminal, a report may unmask corruption, and new evidence may unmask the truth. The word often suggests a decisive revelation, not merely the gradual discovery of information. It can describe literal acts, such as removing a mask at a ceremony, as well as situations in which a person's identity or a hidden fact is exposed. Unmask is understood in British and American English and is useful when emphasizing that secrecy or concealment has ended. It is related in origin to mask and to words such as masque and masquerade, all of which belong to the language of disguise and concealment.
