Answer:
• Monarchy
• Democracy
• Governor
Step-by-step explanation:
Monarchy is derived from a Greek word which translates to one person ruling.
Democracy is derived from a Greek word for rule.
Governor is derived from the Roman word for rule.
All three words are therefore derived from the word rule and it makes sense because today they are used to refer to either those who rule or the process of choosing those who rule.
A monarch and a Governor both have the authority to rule over a certain area and democracy allows us to choose Governors and sometimes Monarchs.
