Art, in its broadest meaning, is the physical expression of creativity or imagination. The word art comes from the Latin ars, which, loosely translated, means "arrangement". Art is commonly understood as the act of making works (or artworks) which use the human creative impulse and which have meaning beyond simple description. 'Art' is often distinguished from crafts and recreational hobby activities. The term creative arts denotes a collection of disciplines whose principal purpose is the output of material for the viewer or audience to interpret. As such, 'art' may be taken to include forms as diverse as prose writing, poetry, dance, acting or drama, music, sculpture, photography, illustration, architecture, and painting. Art may also be understood as relating to creativity, æsthetics and the generation of emotion.
