'anti-democratic' is formed from the prefix 'anti-' (from Greek 'anti' meaning 'against') + 'democratic' (from Greek 'demokratikos', via Latin and French), where 'demo-'/'demos' meant 'people' and '-kratic'/'kratos' meant 'rule or power'.

'anti-' (Greek) combined with 'democratic' (from French 'démocratique' and Latin/Greek roots 'demokratikos') to produce the English compound 'anti-democratic' in modern usage.

Initially it literally meant 'against democracy' and over time has retained that core sense while also coming to describe actions, policies, or attitudes that undermine democratic norms or procedures.
