The Aegean Sea
with its large number of islands is the origin of the term archipelago
An archipelago (/ (listen) PEL-ə-goh), sometimes called an island group or island chain, is a chain, cluster or collection of islands, or sometimes a sea containing a small number of scattered islands.
Indonesia, the Galapagos, Japan, the Philippines, Maldives, the Balearic Isles, the Bahamas, the Aegean Islands, Hawaii, the Canary Islands, and the Azores are all examples of well-known archipelagos.
The word archipelago is derived from the Ancient Greek ἄρχι- (arkhi-, "chief") and πέλαγος (pélagos, "sea") through the Italian arcipelago. In Italian, possibly following a tradition of antiquity, "Archipelago" (from medieval Greek *ἀρχιπέλαγος and Latin archipelagus) was the proper name for the Aegean Sea. Later, usage shifted to refer to the Aegean Islands (since the sea is remarkable for its large number of islands).
