Etymology
Origin of mustache
1575–85; < Middle French moustache < Italian mostaccio; see mustachio
Explanation
A mustache is hair that grows between a person's nose and mouth. Some mustaches are as thin as a pencil line, while others are bushy and full. Salvador Dali was known for his long, curled mustache. If you're trying to grow a mustache, you might start by shaving all your facial hair except the strands that grow above your upper lip. When your mustache becomes luxuriant and ample, you can trim it with scissors and style it with mustache wax. The word mustache comes from the French moustache, which has a Greek root, mystax, "upper lip."
