'antibigotry' originates from Modern English, specifically formed from the prefix 'anti-' (from Greek 'anti' meaning 'against') and the noun 'bigotry' (from French 'bigoterie' / Old French 'bigot').

'bigotry' changed from Old French 'bigoterie' (from 'bigot') and entered English as 'bigotry'; in Modern English the productive prefix 'anti-' was attached to form the compound 'antibigotry'.

Initially, 'bigot' referred to a person seen as excessively pious or hypocritical and 'bigotry' came to mean 'intolerance or prejudice'; 'antibigotry' therefore developed to mean 'opposition to such intolerance'.
