An 'archipelago' is a chain or cluster of islands. The word ''archipelago'' literally means "chief sea", from Greek ''arkhon'' (''arkhi''-) ("leader") and ''pelagos'' ("sea"). In antiquity, the 'Archipelago' (Greek: Αρхιπέλαγος) was the proper name for the Aegean Sea and, later, usage shifted to refer to the Aegean Islands (since the sea is remarkable for its large number of islands). It is now used to generally refer to any island group or, sometimes, to a sea containing a large number of scattered islands like the Aegean.
Archipelagoes are usually found in the open sea; less commonly, a large land mass may neighbour them. Archipelagoes are often volcanic, forming along mid-ocean ridges or hotspots, but there are many other processes involved in their construction, including erosion and deposition.
The four largest modern states that are mainly archipelagos are Japan, the Philippines, New Zealand, and Indonesia.
