Environment may refer either to actual physical surroundings or to social or cultural background factors: an environment of crime and grinding poverty. Milieu, encountered most often in literary writing, refers to intangible aspects of the environment: an exhilarating milieu of artistic ferment and innovation. Ambiance applies to the atmosphere of the surroundings, their mood or tone: an ambiance of ease and elegance. Setting suggests a background that sets something off: a perfect setting for the emerald. Surroundings alludes specifically to the physical aspects of the environment: awoke in strange surroundings; blend in with her surroundings. Unabridged
