Filipino verb voice coordinates the form of the verb with the participant chosen as the clause's pivot. An actor, affected patient, location, beneficiary, or instrument can become the pivot when the verb belongs to an appropriate voice construction. The other participants receive non-pivot or oblique marking.
Traditional descriptions call this system pokus “focus,” so you will encounter labels such as actor focus and object focus. This guide uses actor voice, patient/undergoer voice, locative voice, and benefactive/instrumental voice. “Focus” is a useful pedagogical counterpart, but it does not mean mere spoken emphasis, and the pivot is not a one-to-one copy of the English subject. See Voice and Focus: The Big Picture for the full system.
The central alignment
| Voice | Typical pivot | Basic marker pattern | Sample completed verb |
|---|---|---|---|
| Actor voice | Doer or experiencer | ang/si actor; ng patient | nagluto “cooked” |
| Patient/undergoer voice | Affected or selected entity | ng/ni actor; ang patient | niluto “cooked” |
| Locative voice | Place, goal, or affected site | ng/ni actor; ang location | pinuntahan “went to/visited” |
| Benefactive/instrumental voice | Beneficiary or means | ng/ni actor; ang beneficiary/instrument | ipinagluto / ipinanghiwa |
This table is an orientation, not a license to manufacture verbs. Affix families have lexical restrictions, and a root may allow several voices with meanings that are not perfectly predictable. Full paradigms come later.
Actor voice and patient voice
Start with a controlled pair describing one event:
Nagluto si Ben ng adobo para sa pamilya.
Ben cooked adobo for the family.
Niluto ni Ben ang adobo para sa pamilya.
Ben cooked the adobo for the family.
In the actor-voice sentence, nagluto selects the actor as pivot: si Ben. The food is the non-pivot ng adobo. In the patient-voice sentence, niluto selects the food as pivot: ang adobo. Ben remains the semantic actor, but his name now takes ni, the personal-name counterpart of ng.
English often translates both sentences actively. Patient voice is not merely an English passive in disguise: the actor is commonly expressed, remains an ordinary agent, and is not demoted to an optional “by”-phrase. The two Filipino clauses differ in which participant the grammar and discourse organize as pivot.
Pivot choice is not just definiteness
Patient pivots are commonly specific and identifiable, which is why ang adobo was translated as “the adobo.” But ang is not the article “the,” and ng does not automatically mean “a/some.” Actor voice can retain a specific, demonstrative patient as non-pivot:
Bumili si Mara ng librong iyon kahapon.
Mara bought that book yesterday.
Ng librong iyon is unmistakably specific because of iyon “that,” yet it remains non-pivot in this actor-voice clause. Voice choice interacts with specificity, affectedness, event structure, and what the conversation is centered on; no English article can decide the voice by itself.
Animacy also influences what speakers tend to discuss as actors or beneficiaries, but it does not mechanically assign voice. A human actor can be non-pivot in patient voice, as ni Ben shows. With common human nouns, the ordinary markers are still ang/ng/sa; si/ni/kay are selected specifically by personal-name constructions.
Other voices select other relations
Locative voice can make a destination or affected location the pivot:
Pinuntahan ni Liza ang klinika bago magtrabaho.
Liza went to the clinic before work.
The clinic is not an English agent or patient, but ang klinika is the pivot selected by pinuntahan. In actor voice, a related clause would normally use pumunta si Liza sa klinika, with Liza as pivot and the clinic as an oblique destination.
Benefactive voice can select the person for whom something is done:
Ipinagluto ni Ben ng lugaw ang lola niya.
Ben cooked porridge for his grandmother.
Here ang lola niya is the beneficiary pivot, ni Ben is the non-pivot actor, and ng lugaw is the non-pivot thing cooked. Instrumental voice can instead select the means used:
Ipinanghiwa ni Rosa ng gulay ang kutsilyong ito.
Rosa used this knife to cut vegetables.
Ang kutsilyong ito is the instrument pivot. The -ng in kutsilyong is a linker connecting kutsilyo to ito; it is not the separate marker ng before gulay. Linkers build phrases, while voice and phrase markers organize the clause.
Benefactive and instrumental patterns are fully standard, but individual verb forms are less freely predictable than a compact chart suggests. Some are common lexical items; others sound forced even if their affixes appear mechanically possible. Learn attested verb families rather than attaching a “focus affix” to any root at will.
Aspect operates inside every voice
Voice does not replace aspect. A speaker chooses both an event phase and a pivot alignment:
Nagluluto si Ben ng sopas ngayon.
Ben is cooking soup now.
Niluluto ni Ben ang sopas ngayon.
Ben is cooking the soup now.
Both verbs are incompleted: the cooking is underway. The first is actor voice; the second is patient voice. Completed nagluto/niluto and contemplated magluluto/lulutuin maintain related alignments, although their formation must be learned with each family.
Questions reveal what the clause is centered on
Filipino commonly chooses a voice that allows the participant being identified to align with the question construction.
— Sino ang bumili ng gamot? — Si Mara ang bumili.
— Who bought the medicine? — Mara was the one who bought it.
The unknown is the actor, so the verb is actor voice. Now compare a question about the purchased item:
— Ano ang binili ni Mara? — Gamot ang binili niya.
— What did Mara buy? — Medicine was what she bought.
The unknown is the patient, so binili is patient voice. English leaves “buy” active in both questions; Filipino makes a grammatical alignment choice. This is the practical value of “focus”: the construction helps place the participant at issue in the pivot relation.
Negation does not undo that alignment:
Hindi binili ni Mara ang pulang bag.
Mara did not buy the red bag.
Hindi negates the patient-voice predicate binili; ang pulang bag remains the pivot. Pulang contains the linker -ng, joining pula “red” to bag.
Predicate-first order remains the baseline
Voice controls alignment, not a rigid English SVO template. The predicate normally begins the clause:
Abala si Nena, pero nagluto pa rin siya ng hapunan.
Nena was busy, but she still cooked dinner.
The nonverbal predicate abala needs no form of “to be,” and verbal nagluto likewise precedes its actor pivot. A fronted ay topic is possible (formal) in exposition or contrastive in speech, but ay is neither a copula nor the source of voice.
Common Mistakes
1. Combining a patient-voice verb with actor-voice markers
❌ Niluto si Ben ng adobo.
Incorrect for ‘Ben cooked the adobo’ — the verb and markers encode conflicting alignments.
✅ Niluto ni Ben ang adobo.
Ben cooked the adobo.
Patient-voice niluto requires the actor as ni Ben and the patient pivot as ang adobo.
2. Combining an actor-voice verb with patient-voice markers
❌ Nagluto ni Ben ang adobo.
Incorrect for the intended actor-voice clause.
✅ Nagluto si Ben ng adobo.
Ben cooked adobo.
Actor-voice nagluto selects si Ben as pivot, while ng adobo is non-pivot.
3. Treating the patient pivot as the actor because it resembles an English subject
❌ Ang adobo ang niluto kay Ben.
Incorrect for ‘Ben cooked the adobo’; kay Ben marks Ben as an oblique relation, not the actor.
✅ Ang adobo ang niluto ni Ben.
The adobo was what Ben cooked.
In this fronted identificational construction, ni Ben still marks the non-pivot actor. The first ang adobo identifies the selected patient.
4. Forcing English SVO order with ay
❌ Nagluto ay si Ben ng adobo.
Incorrect — ay cannot be inserted after the verb as an English-style auxiliary.
✅ Nagluto si Ben ng adobo.
Ben cooked adobo.
The separate sentence Si Ben ay nagluto ng adobo is appropriate (formal) or when “as for Ben” is contrastive. It should not become a default template merely because English begins with “Ben.” The correction removes false copula insertion and restores neutral predicate-first information structure without changing the voice.
Key Takeaways
Voice selects the pivot and coordinates the verb with ang/si, ng/ni, and sa/kay phrases. Actor voice centers the actor; patient, locative, benefactive, and instrumental voices can center other roles. Aspect independently describes the event's phase. Voice choice is meaningful and partly lexically restricted, not a mechanical conversion between English active and passive sentences.
