This particle is made use of, when the nominative produces on the accusative, that which the root signifies. It is also a nominative of this particle the cause or place where the effect is produced. The active voice is conjugated according to the rules laid down for naca potential. The scholar must pay particular attention to this particle in order to use it properly in its two acceptations.
The potential naca, is compounded but with roots of active verbs, and the causal with those of neuter verbs and of adjective nouns.
The present and past tenses of this passive are formed by putting guica, before the root and an after; the future and imperative with ca, before and an after: and the infinitive mood placing pagca or ca, before.
Remark. At Cebú and Bohol provinces is very often used na, instead of guica, with an invariably after the root. Examples:
| Of what illness did John die? | ¿Onsay namatyan or guicamatyan ni Juan? |
| He was struck with fever. | Ang hilanat maoy namatyan nia. |
2.a When speaking with this particle the natives insert between the subject and the verb, the verb maoy or mao, and ang, to express with more energy and precision the causality idea.
Remark. The recoleto P. Zueco, of great authority on the matter says, that the verb mao, must be always inserted between, both in active and passive voices, when speaking with the particle naca causal. Thus:
ACTIVE.
| The medicine did well with the sick. | Ang tambal maoy naca-ayo sa masaquit. |
PASSIVE.
