'otherworldliness' originates from the combination of 'other' and 'worldliness', where 'other' meant 'different or distinct' and 'worldliness' referred to 'concern with material values or ordinary life'.

'otherworldliness' evolved from the Middle English term 'otherworldly', which combined 'other' and 'worldly', eventually forming the modern English noun 'otherworldliness'.

Initially, it meant 'pertaining to another world', but over time it evolved into its current meaning of 'a sense of detachment from the mundane'.
