1. From the Tagalog word "lusong":
* This theory suggests that "Luzon" comes from the Tagalog word "lusong," a large wooden mortar used for pounding rice.
* It is thought that the island may have been named after the abundance of "lusong" used by the indigenous people.
2. From the Arabic word "luz":
* This theory proposes that "Luzon" originated from the Arabic word "luz," meaning "island" or "coast."
* This theory is supported by the fact that Arab traders had contact with the Philippines as early as the 10th century.
It's important to note that both theories are speculative, and there's no definitive proof for either.
It's also possible that the name "Luzon" evolved over time, incorporating elements from both Tagalog and Arabic languages.
Regardless of its exact origin, the name "Luzon" has been used to refer to the largest island in the Philippines for centuries.
