atmospheric

The word 'atmospheric' is built upon the noun 'atmosphere', which entered English in the 17th century from Modern Latin 'atmosphaera'. This Latin term was itself a compound of two Greek words: 'atmos' (vapor, steam) and 'sphaira' (ball, globe). The original, literal concept was that of a globe or enveloping sphere of vapor surrounding a celestial body. The adjective-forming suffix '-ic' was then appended, meaning "pertaining to". Over time, as scientific understanding evolved, the meaning of 'atmosphere' expanded from a literal gaseous envelope to also signify the pervading tone or mood of a place, a metaphorical extension of its physical sense of "surrounding environment". Thus, 'atmospheric' logically describes both the physical properties of the air and the intangible, enveloping quality of an ambiance.
