'anti-dynastic' originates from Greek and Modern English: specifically the prefix 'anti-' from Greek 'anti' meaning 'against', combined with English 'dynastic', which derives from French 'dynastie' < Late Latin 'dynastia' < Greek 'dynasteia', where the root 'dyn-' meant 'power' or 'to be able'.

'anti-dynastic' was formed in modern English by attaching the Greek-derived prefix 'anti-' to the adjective 'dynastic' (itself developed from Greek 'dynasteia' via Latin and Old French), eventually becoming the compound adjective 'anti-dynastic' in English usage.

Initially it meant 'against dynastic rule' and over time it has retained that core meaning, used to describe opposition to hereditary ruling families or dynastic influence.
