However, some scholars believe it might be derived from the Tagalog word "pinatu-bo", which means "to sprout" or "to grow". This could refer to the vegetation that grows on the slopes of the volcano.
Others suggest it might be related to the word "pinatubo", meaning "to make something sharp", perhaps referencing the volcano's peak or the sharp edges of the surrounding rocks.
Ultimately, the exact meaning of "Pinatubo" remains somewhat ambiguous and open to interpretation.
