Etymology
Origin of mask
First recorded in 1525–35; from Middle French masque, perhaps directly from Italian maschera “mask, disguise,” from unattested pre-Latin maskara, an extended form of unattested mask-, probably with the original sense “black” (blackening the face being a simple form of disguise); another development of the same base is early Medieval Latin masca “witch, ghost” (also, “mask”); see mascot
Explanation
A mask is a disguise that covers just your face. Your Halloween costume might include a scary monster mask and a furry suit with a tail, or maybe you just wear that for fun. You can wear a mask to conceal your identity, to dress up as a character for a party or holiday, to scare someone, or to make someone laugh. Robbers sometimes wear masks so they can't be identified, and an actor might wear a mask while playing the role of a rabbit in a play. Other masks are useful, including masks that protect patients from germs and masks that keep skiers' faces warm.
