The term 'commune greek' refers to four distinct words: deme (4 letters), AMANA (5 letters), este (4 letters), and ASTI (4 letters). Deme is a small administrative division in ancient Greece, while AMANA is a communal religious society that originated in the United States in the 19th century. Este is a commune in Italy, and ASTI is a commune in France. All four of these words refer to a type of communal living arrangement, which is why they are grouped together under the term 'commune greek'.
