Actor voice selects the actor-like participant as the clause's pivot. That participant takes the ang series, a core patient or produced theme commonly takes ng, and a location, destination, or recipient commonly takes sa. This is a voice-and-marker alignment, not Filipino's version of English subject–verb–object order.
The central marker map
The appropriate form depends both on grammatical role and on phrase type. Common nouns use ang/ng/sa, personal names use si/ni/kay in the corresponding environments, and pronouns have separate ang-, ng-, and sa-forms.
For the introductory marker system, review marker choice with actor-voice verbs.
| Participant in actor voice | Common phrase | Personal name | Pronoun |
|---|---|---|---|
| actor pivot | ang | si/sina | ako, ka, siya, tayo, kami, kayo, sila |
| core non-pivot patient/theme | ng | depends on the verb's lexical frame | not normally an ordinary personal-patient complement |
| location/destination | sa | kay/kina where personal reference is appropriate | sa akin, sa iyo, sa kaniya... |
| recipient/endpoint | sa | kay/kina | sa-form pronoun |
Nag-ayos ang mga boluntaryo ng lumang aklatan nitong Sabado.
The volunteers fixed up an old library this Saturday. (actor voice)
Ang mga boluntaryo is the actor pivot selected by nag-ayos. Ng lumang aklatan is the non-pivot patient. English places the volunteers before the verb, but Filipino would preserve these roles even if heavier phrases caused a different postverbal order.
Naghatid si Pilar ng mainit na pagkain sa mga bantay bago maghatinggabi.
Pilar delivered hot food to the guards before midnight. (actor voice)
Here si Pilar is pivot, ng mainit na pagkain is the conveyed theme, and sa mga bantay is the recipient. Calling both postverbal phrases “objects” hides the distinction that Filipino markers make.
The actor pivot is not always a deliberate agent
“Actor” is a grammatical cover term. It includes deliberate doers, experiencers, movers, and the sole participant in many changes of state.
Nanginig ang bata nang marinig niya ang malakas na kulog.
The child trembled when he or she heard the loud thunder. (nonvolitional actor-voice pivot)
Dumulas si Ramon sa maputik na daan pero agad siyang tumayo.
Ramon slipped on the muddy road but immediately stood up. (nonvolitional actor-voice pivot)
Neither participant intentionally caused the event. They nevertheless take ang/si because the established verb forms select their actor-like sole participant as pivot. Animacy and volition influence which verbs sound plausible, but they do not define the marker series.
Pronoun pivots use ang-forms and normally occur early as enclitics.
Nagpadala kami kahapon ng mga kumot sa sentro ng paglikas.
We sent blankets to the evacuation center yesterday. (exclusive we; actor voice)
Kami excludes the addressee. Inclusive tayo would include the person being spoken to. The early position of kami follows clitic syntax; it does not turn the later ng phrase into a pivot.
Ng patients can be substantial and identifiable
A core patient in actor voice is often newly introduced, but it need not be vague, inanimate, or unimportant.
Nagbasa si Imani ng liham na iniwan ng kaniyang ama sa mesa.
Imani read the letter that her father left on the table. (identifiable ng-marked patient)
The relative clause identifies a particular letter. It remains ng liham because nagbasa selects Imani, not the letter, as pivot. Switching ng to ang without changing the verb would break the alignment.
Personal patients require special care. Do not mechanically use ni + name where a common patient had ng. Ni normally marks a personal non-pivot actor or possessor. Many actor-voice verbs construe a person as an endpoint and use kay; others favor a patient-voice construction.
Tumawag si Ruben kay Aling Cora para kumpirmahin ang iskedyul.
Ruben called Aling Cora to confirm the schedule. (actor voice; personal endpoint)
Tinawagan ni Ruben si Aling Cora para kumpirmahin ang iskedyul.
Ruben called Aling Cora to confirm the schedule. (patient/locative voice; personal pivot)
These are not obtained by changing markers alone: tumawag and tinawagan belong to different voice frames. The exact frame is lexical, so learn a verb with its normal participants.
Voice changes the whole alignment
Compare two descriptions of one preparation event:
Nagluto si Belen ng pansit para sa pulong.
Belen cooked noodles for the meeting. (actor voice)
Niluto ni Belen ang pansit para sa pulong.
Belen cooked the noodles for the meeting. (patient voice)
Actor voice selects si Belen and marks the noodles with ng. Patient voice selects ang pansit and changes the actor to ni Belen. Both clauses are ordinary and both naturally have active English translations. Patient voice is not an optional English passive added after the sentence has already been built.
Discourse helps motivate the choice. The actor-voice version readily reports what Belen did or introduces the refreshments. The patient-voice version readily continues a discussion of the refreshments or presents their preparation as the relevant result. These are tendencies, not absolute definiteness rules.
Aspect, negation, and order do not erase the map
Completed, incompleted, and contemplated aspect can change while the actor remains pivot.
Nag-aayos ang mga tekniko ng sirang antena sa bubong.
The technicians are repairing a broken antenna on the roof. (incompleted actor voice)
Mag-aayos ang mga tekniko ng isa pang antena bukas.
The technicians will repair another antenna tomorrow. (contemplated actor voice)
Negation and polar questions also preserve alignment.
Hindi nagdala si Vina ng kopya dahil naiwan niya iyon sa bahay.
Vina did not bring a copy because she left it at home. (negative actor voice)
Nag-iwan ba ang drayber ng mensahe sa himpilan?
Did the driver leave a message at the station? (actor-voice question)
In both, the actor takes the ang series and the patient takes ng. Hindi and ba affect polarity or clause type, not voice.
A short exchange
A: Sino ang nagdala ng ekstrang baterya? B: Nagdala si Farid ng dalawa para sa pangkat.
A: Who brought an extra battery? B: Farid brought two for the group.
The question asks for the actor pivot, so actor voice is natural. The answer supplies si Farid as that pivot; ng dalawa is an elliptical non-pivot patient meaning “two [batteries].”
Common Mistakes
Giving both actor and patient pivot marking
❌ Nagtahi ang mananahi ang punit na kurtina.
Incorrect — actor-voice nagtahi already selects the tailor as pivot.
✅ Nagtahi ang mananahi ng punit na kurtina.
The tailor sewed a torn curtain. (actor voice)
Marking a destination as a core patient
❌ Pumunta si Hana ng munisipyo pagkatapos mananghalian.
Incorrect — the municipal hall is a destination and requires sa.
✅ Pumunta si Hana sa munisipyo pagkatapos mananghalian.
Hana went to the municipal hall after lunch.
Combining patient-voice markers with an actor-voice verb
❌ Tumawag ni Lena si Berto tungkol sa bayarin.
Incorrect — tumawag cannot take a ni-marked actor and si-marked endpoint in this frame.
✅ Tumawag si Lena kay Berto tungkol sa bayarin.
Lena called Berto about the bill. (actor voice)
Patient-oriented Tinawagan ni Lena si Berto is also grammatical, but it chooses Berto as pivot and packages the event differently.
Reading the first noun after the verb as the actor
❌ Kumain ang pansit ng mga manlalaro pagkatapos ng ensayo.
Incorrect for the intended meaning — this marking makes the noodles the actor and the players the patient.
✅ Kumain ng pansit ang mga manlalaro pagkatapos ng ensayo.
The players ate noodles after practice. (actor pivot follows the patient)
Key Takeaways
- Actor voice selects an actor-like participant as the ang-series pivot.
- A core patient commonly takes ng; locations, destinations, and recipients commonly take sa/kay/kina.
- Personal participants follow lexical verb frames, so ni is not a mechanical personal replacement for patient ng.
- Aspect, negation, questions, and flexible postverbal order do not change the underlying marker map.
- Actor and non-actor voices reorganize the viewpoint of an event; they are not simply English active and passive.
