Where did the word art originate?
Art comes from Latin ars, artis. The core meaning in Latin is practical skill (compare with English art, artful in the sense of cunning). In Latin the word also means professional skill and was applied increasingly to skill in creating poetry and music. In the course of time it was also applied more specifically to painting and sculpture.
The word music originates from the Greek words mousa (muse) musikos (pertaining to the muses) and mousike (techne) "(art) of the muses." It had been handed down to us with its current meaning by the Latin word musica (the art of music). The Latin word also referred to poetry as it creates a musical impression with words.
