A luthier (pronounced /ljuːˈti.ər/) is someone who makes or repairs stringed instruments. The word luthier comes from the French word luth which means “lute”.
The craft of lutherie is commonly divided into two main categories: stringed instruments that are plucked or strummed, and those that are bowed.[1] Since bowed instruments require a bow, the second category includes a subtype known as an archetier, a French word meaning one who makes bows.[2] While the division of luthiers into different categories may seem arbitrary, there are those who are passionate about the difference between these branches of the craft.[3][4]
