'anti-ministerial' is a modern English compound formed from the prefix 'anti-' (from Greek 'anti' meaning 'against') + 'ministerial' (from Latin 'ministerialis' via English 'minister' + adjectival suffix '-ial').

'ministerial' derives from Latin 'minister' ('servant' or 'attendant') which passed into Old French and Middle English; the English prefix 'anti-' was attached in modern usage to form 'anti-ministerial' meaning 'against ministers' or 'against ministerial authority'.

Originally composed simply to indicate opposition 'against ministers' or 'the ministry,' its modern usage retains that basic sense and is typically used to describe attitudes, actions, or rhetoric hostile to ministerial authority or policies.
