Here's a breakdown:
* pag- - This is a prefix used to indicate an action or process.
* lalang - This means "to create" or "to form."
* ning - This is a preposition that means "of" or "from."
* amanu - This is the Kapampangan word for "word."
Therefore, "pag-lalang ning amanu" literally translates to "the creation of words," which accurately captures the concept of "word building."
