When the root begins with a dental consonant as
| dapò | (to approach) |
| tábon | (to cover) |
| surát | (to write) |
the formation of the plural consists in replacing the first consonant by n, as
| napó, nabon, nurat, |
whose first syllable is doubled[74], as
| nanapo, nanabon, nunurat, |
to which the particle na is prefixed as
| nanánapó, nanánabon, nanúnurat, |
the final form.
If the root commences with any other consonant, the plural is formed by doubling the first syllable of the root, and by prefixing the particle nan to the root so transformed. Examples:
