what does the name Hawaii means?

A couple of theories exist on the origin of the name Hawaii.
1) One theory has it that the name comes from a combination of the words "Hawa" and "ii" and means a small or new homeland; "Hawa" meaning a traditional homeland and "ii" meaning small and raging.
2) The other theory is that the name comes from the traditional discoverer of the islands, Hawaii Loa.

Many believe the name Hawaii was adapted from the name Hawaiki, the name for a mythical homeland of all Polynesians. Others believe it is a variation of a South Pacific island Raiatea, which was called Havaii at the time of migration.
