This word is the origin of the term "politics", which refers to the activities associated with the governance of a country or other area, especially the debate or conflict among individuals or parties having or hoping to achieve power.
While "politikos" itself doesn't directly translate to "science of managing government", it is the foundation of many related terms, including:
* Politology: The study of government and political processes.
* Politician: A person actively involved in party politics.
* Policy: A course or principle of action adopted or proposed by a government, party, business, or individual.
Therefore, while there might not be a single Greek root word with a precise meaning of "science of managing government", "politikos" serves as the foundation for various terms that capture the essence of governing and its study.
