'atmosphereless' originates from English, composed of the noun 'atmosphere' (from Greek 'atmós' meaning 'vapor' and 'sphaira' meaning 'sphere') and the suffix '-less' (from Old English 'lēas' meaning 'free from, without').

'atmosphere' entered English via French 'atmosphère' in the 17th century from Greek 'atmós' + 'sphaira'; the suffix '-less' comes from Old English 'lēas' and combined with 'atmosphere' to form the compound adjective 'atmosphereless' in modern English.

Initially, 'atmosphere' meant 'a vapor or gaseous envelope' and '-less' meant 'without'; together 'atmosphereless' has meant 'without an atmosphere', and this basic sense has remained stable.
