-archy

Also ‑arch.

Government; rule of a particular type; a chief or ruler.

Greek arkhēs, ruler; arkhein, to rule.

Words in ‑archy are abstract nouns for types of government, leadership, or social influence or organization. They correspond to nouns in ‑arch for a person or people who rule or command in that way. For example, a monarch (Greek monos, alone or single) is a sovereign head of state, in a type of government called monarchy.

The ending is somewhat active, with terms being created for occasional use or wordplay, such as cupidarchy, a state built on cupidity, or ergonarchy (Greek ergon, work), one ruled by the work ethic.

For more examples, See also ‑cracy.
