How to Polis, 101, Part IIa: Politeia in the Polis

The English word "police" actually comes from the Ancient Greek "polis".

E.g. from the etymology section of the Wikipedia article on police:

"First attested in English in the early 15th century, originally in a range of senses encompassing '(public) policy; state; public order', the word police comes from Middle French police ('public order, administration, government'), in turn from Latin politia, which is the romanization of the Ancient Greek πολιτεία (politeia) 'citizenship, administration, civil polity'. This is derived from πόλις (polis) 'city'."

Same in Sweden :D
