If the root commences with a labial consonant, except m, pag is transformed into pam, and then the labial consonant disappears. Examples:
| from | “báyad” | (to pay), | pagbáyad, | pl. pamáyad. |
| “pilì” | (to select), | pagpilì, | pl. pamilì. |
When the root begins with m, pag is transformed into pan, the m of the root remaining in it. Example:
| from | “múlay” | (to teach), | pagmúlay, | pl. panmúlay. |
If the root commences with any other consonant, pag is replaced by pan, the said consonant being then suppressed except when it is a g or h. Examples.
| from | “hapon” | (to perch), | paghápon, | pl. panhápon, |
| from,, | “gúbat” | (to invade), | paggúbat, | pl. pangúbat, |
| from,, | “búao” | (to visit), | pagdúao, | pl. panúno, |
| from,, | “tubò” | (to grow), | pagtubò, | pl. panubò, |
| from,, | “surát” | (to write), | pagsurát, | pl. panurát. |

When the root commences with a vowel, this particle is simply prefixed to the root. As,
