Etymology

Borrowed from Italian Tripoli, from Latin Tripolis, from Ancient Greek Τρίπολις (Trípolis), from τρι- (tri-, “three”) + πολις (polis, “city, city-state”). In reference to American cities, after US actions off Tripoli in Libya during the First Barbary War. Doublet of Tripolis, Tirebolu, and Tripura.

From modern Greek Τρίπολη (Trípoli) used from the 19th century in place of Byzantine Greek Τριπολιτσά (Tripolitsá), probably from Slavic Droboliza.
