oná (to commence), maonaoná (provocative, quarrelsome),

and in cases where the root has more than two syllables, or if not, where its last vowel is preceded by more than two consonants or is pronounced separately from the consonant or consonants preceding it, then this prefix is employed in combination with the interfix ro preceded by the first consonant and vowel of the root or by the vowel only if the root begins with a vowel, as

from catúrog, macarocaturóg,
from,, bányac, (to kick), maharobányac,
from,, síd-ap, (to look at), masirosíd-ap,
from,, arába, maaroarabá,
from,, ígham, (to grunt), mairoígham,
from,, ós-og (to draw near from afar), maoroós-og.

When the particle ma conveys the idea of passive potentiality or possibility, it is used with the interfix r combined with the first vowel of the root. The r with its complementary vowel is put after the first syllable of the root. As,

from bóong (to break), maboroóng (brittle)
from,, abót (to reach), maarábot (attainable).

The particle ma is frequently replaced by the prefix ig or i combined with the interfix r or its substitutes, as

from tambal (to cure), igtarámbal or itárambal (medicine),
from,, surat (to write), isusúrat (thing to write with).
Mag and the r.

The prefix mag bears the idea of forcible, necessary, or continuous agency. It is employed with the interfix r combined with and before the first vowel of the root. This combination is placed between the first and the second syllable of the root. But when there is an r in the root, the interfix r is replaced by the first consonant of the [[19]]said root. If the root begins with a vowel, the interfix r is sometimes suppressed, the said first vowel being used instead of the interfix. As,

from sódoy (to stroll about), magsotodóy (one who strolls about)
from,, bilíng̃ (to seek or search), magbiríling̃ (searcher),
from,, siríng̃ (to request), magsisíring̃, (petitioner), not magsiríring̃,
from,, ósoc (to set up), mag-orosóc (person designed to set up),
from,, arót (to cut the hair), mag-aárot (barber).
