Observations: 1. There are verbals formed with ma combined with the interfix r or its substitutes. This formation takes place only in the intransitive verbs commencing with the particle ca which then conveys the idea of passivity. As,
| from | caauód | (to be ashamed), | macaaráuod | (shameful), |
| from,, | cabórong̃ | (to be confused), | macabobórong̃ | (confusing), |
| from,, | casína | (to be angry), | macasisína | (odious). |
2. The infinitives of the verbs, which are always preceded by the particle pag, are frequently employed as substantives. In such cases the particle pag is transformed in the plural, its g being then replaced by the letter ng̃ if the root begins with a vowel or a guttural consonant, except g, or by the consonant n when the root commences with a dental consonant, or by the m if it begins with a labial. In the plural, the roots commencing with a consonant lose said consonant. When the root begins with a nasal or with the guttural g, said consonant is preserved and the g of pag is replaced by n. Examples:
from arò (to ask), cáon (to eat), dáop (to approach) bása (to read), ng̃oyng̃oy (to groan), gábot (to, pull), we have:
| SINGULAR | PLURAL | |
| pag-arò | (asking) | pang̃arò, |
| pagcáon | (eating) | pang̃áon, |
| pagdáop | (approaching) | panáop, |
| pagbása | (reading) | pamása, |
| pagngoyngoy | (groaning) | panngóyagoy, |
| paggábot | (pulling) | pangábot, |

3. The infinitives of roots commencing with the particle ca are also used as substantives, and then with or without the prefix pag.
| from | cabido | (to be sorry), | pagcabídò, cabídò, | (sorrow). |
In such cases, the affix an or on is sometimes employed, as
| from | casáquit | (to be sad), | casaquítan | (sadness), |
| from,, | casína | (to be angry), | casinahón | (anger). |
