'anticensorial' originates from Modern English, specifically formed from the prefix 'anti-' (from Greek 'antí') meaning 'against' combined with 'censorial' ultimately from Latin 'censor' meaning 'censor' or 'one who assesses'.

'anticensorial' was created in English by combining 'anti-' + 'censorial'; 'censorial' derives from Latin 'censor' which passed into Old French (e.g. 'censeur'/'censor') and Middle English before producing English derivatives like 'censor' and 'censorial'.

Initially formed to convey being 'against the censor' or 'against censorial action'; it has come to mean generally 'opposed to censorship' or 'in favor of freedom of expression'.
