Did You Know?
Vanguard and avant-garde both derive from the Anglo-French word avantgarde, itself from avant, meaning "before," and garde, meaning "guard." In medieval times, avantgarde referred to the troops that marched at the head of the army.
English speakers retained that meaning when they adopted vanguard in the 15th century. Avant-garde, which is now used in English to refer to a group of people who develop new and often very surprising ideas in art, literature, etc., didn't make its own English debut until almost 400 years later.
