Definition of the word disguise

The word "disguise" has its roots in the 14th century Old French phrase "desguiser," which means "to cover up" or "to conceal." This phrase is derived from the Old French words "des-" meaning "without" and "guiser" meaning "to dress" or "to put on clothes." The word "disguise" entered the English language in the 1420s and initially meant "to change one's appearance by putting on different clothes" or "to conceal one's identity." Over time, the meaning of the word expanded to include the idea of hiding or concealing one's true nature, whether it be a physical appearance or a personality trait. Today, the word "disguise" is used in a variety of contexts, including theater, costume design, and even espionage, where it can refer to the act of hiding one's true identity or intentions.
