What's in the name?

This information was actually from the internet. I’ll just be honest, I won’t be able to know anything about the Bagobos without the internet. So,I’m just gonna state the things I know about them. The first thing I know about them is about their name. The word Bagobo comes from the word “bago” which means new and “obo” which means growth. Maybe obo was changed to tubo which means grown in Waray-waray.
