Busking is the practice of performing in public places, for tips. People engaging in this practice are called buskers.
The word "busk" comes from the Spanish root word "buscar", meaning "to seek" – buskers are literally seeking fame and fortune. The Spanish word "buscar" in turn evolved from the Indo-European word *"bhudh-skō" (to win, conquer) via the Celtic word "boudi-" (victory).
The term "busking" was first noted in the English language around the middle 1860s in Great Britain. Up until the 20th century buskers were commonly called minstrels in America, Europe and other English-speaking lands.
