Where does the name Samoa come from who named this island Samoa?

The origin of the name "Samoa" is believed to have several different interpretations, but the most common explanation is that it is derived from the Polynesian word "Sāmoa", meaning "sacred to Moa". Moa is a legendary figure in Samoan mythology, who is said to have come from the island of Hawaiki and settled in the Samoan Islands. The name Samoa may also have come from the Samoan word "sa", which means "sacred", and "moa", which refers to a type of hen or chicken. Hence, "Samoa" can be interpreted as "sacred to the hen" or "sacred land".

It's important to note that the naming of the Samoan Islands is deeply rooted in Samoan culture and history, and there may be other explanations or interpretations of the origin of the name. As with many ancient names, the true etymology of "Samoa" may never be fully known.
