'non-sufferer' originates from English, formed by the negative prefix 'non-' (from Latin 'non', meaning 'not') combined with the noun 'sufferer' (from the verb 'suffer').

'sufferer' developed in Middle English from the verb 'suffer' (from Latin 'sufferre' = 'sub-' + 'ferre', meaning 'to bear'), and the compound 'non-sufferer' is a modern formation applying the productive English prefix 'non-' to that noun.

Initially the elements referred literally to 'not' + 'one who bears/experiences (suffering)'; over time the compound has been used more generally to mean someone not affected by a specified pain, disease, or hardship rather than a strictly literal absence of all suffering.
