The prefix i- forms an important benefactive/instrumental voice family. In many common verbs it selects a theme that is transferred, placed, sent, applied, worn, or put into a form: ibigay “give,” ilagay “put,” itapon “throw away,” isulat “write down,” and isuot “put on/wear.” The selected participant is the ang/si pivot; the actor takes an ng/ni form.
The manifest title uses the conventional label conveyance voice, which captures the frequent idea of moving or directing a theme. This guide uses benefactive/instrumental (i-) voice as the primary umbrella label because established i- families also select beneficiaries or instrument-like participants. No single English preposition or verb unifies every use.
The larger aspect-and-voice paradigm explains how pivot selection and event phase intersect. This sequence develops that intersection specifically for i-.
Core frames
| Basic form | Selected pivot | Other participants | Typical function |
|---|---|---|---|
| ibigay | thing transferred | giver with ng/ni; recipient with sa/kay | give or hand something |
| ilagay | thing placed | placer with ng/ni; destination with sa | put something somewhere |
| isulat | content put into writing | writer with ng/ni; surface/destination with sa | write something down |
| ipukpok | instrument used | actor with ng/ni; target with sa | use something for striking |
| ibili | beneficiary | buyer with ng/ni; purchased item with ng | buy something for someone |
The last two rows show why “conveyance” is useful but incomplete. The lexical verb decides which semantic role i- selects.
Ibigay mo kay Aling Rosa ang sobre bago ka umalis.
Give the envelope to Aling Rosa before you leave.
The understood actor is marked by mo, ang sobre is the conveyed pivot, and kay Aling Rosa is the personal recipient. English calls the recipient an indirect object; Filipino does not make it pivot in this construction.
Ilagay ninyo sa ibabang estante ang mga malinis na tuwalya.
Put the clean towels on the lower shelf.
The towels are the placed pivot. The shelf remains an oblique destination with sa.
Aspect morphology
The prefix i- remains visible across the paradigm. Begun forms add -in- inside the root, while incompleted and contemplated forms also copy the root's first consonant–vowel sequence.
| Root | Basic | Completed | Incompleted | Contemplated |
|---|---|---|---|---|
| bigay | ibigay | ibinigay | ibinibigay | ibibigay |
| tapon | itapon | itinapon | itinatapon | itatapon |
| sulat | isulat | isinulat | isinusulat | isusulat |
| lagay | ilagay | inilagay | inilalagay | ilalagay |
With consonant-initial roots, completed -in- appears before the root's first vowel: i-b-in-igay, i-t-in-apon. Before root-initial l, the begun marker surfaces as ni- after i-, producing inilagay, not ilinagay.
Controlled voice comparison
Nagbigay si Celia ng kopya kay Ruben pagkatapos ng pulong.
Celia gave Ruben a copy after the meeting.
Ibinigay ni Celia kay Ruben ang kopya pagkatapos ng pulong.
Celia gave Ruben the copy after the meeting.
Actor-voice nagbigay selects si Celia and leaves the theme as ng kopya. Benefactive/instrumental i- form ibinigay selects ang kopya, changes Celia to ni Celia, and retains recipient kay Ruben. Both English translations are active; this is a Filipino pivot contrast, not English active versus passive.
Specificity often favors an identifiable i- pivot, but it is not a mechanical article rule. Actor voice can have a specific ng theme in context, and voice choice also responds to discourse and lexical constraints.
Beneficiary and instrument-like pivots
Some simple i- families select a beneficiary:
Ibili mo ng prutas ang lola mo kapag dumaan ka sa palengke.
Buy your grandmother some fruit when you pass through the market.
Ang lola mo is the beneficiary pivot, while ng prutas is the item. This differs from conveyance Ibigay mo kay Lola ang prutas, where the fruit is pivot and Lola is recipient.
An established i- verb can instead select something used as a means:
Ipinukpok ni Dario sa pako ang maliit na martilyo.
Dario used the small hammer to strike the nail.
The hammer is the instrument-like pivot. More transparently instrumental families often use ipang-; simple i-, ipang-, and ipag- must be learned as related but distinct lexical patterns.
Questions, negatives, and a short exchange
Hindi itinapon ni Mina ang lumang resibo dahil kailangan pa iyon.
Mina did not throw away the old receipt because it was still needed.
Negation does not alter the pivot frame: ni Mina remains actor and ang lumang resibo remains selected theme.
—Saan mo ilalagay ang ekstrang upuan? —Ilalagay ko iyon sa tabi ng pinto.
—Where will you put the extra chair? —I will put it beside the door.
The contemplated verb appears in both turns. Saan asks for the destination, while the chair remains pivot as ang ekstrang upuan/iyon.
Lexical limits and genuine variation
A root is a family of constructions, and one citation form hides the derivational system. Sulat supports actor-voice sumulat/magsulat, patient-voice sulatin, locative sulatan, and i- form isulat. Their English translations overlap, but their pivots and collocations differ.
Some speakers alternate i- with a patient-voice form in particular contexts, especially where the theme can be construed either as an affected object or as content transferred into a location. This is lexical and discourse-conditioned variation, not free substitution. Neutral standard Filipino also has occasional in- placement variants with vowel-initial bases; learn the established surface form of each common verb rather than extrapolating blindly.
Common Mistakes
Marking the actor as pivot
❌ Ibinigay si Celia ang kopya kay Ruben.
Incorrect — ibinigay selects the conveyed copy, so Celia must be non-pivot.
✅ Ibinigay ni Celia kay Ruben ang kopya.
Celia gave Ruben the copy.
Treating i- as English “to”
❌ Ibigay mo ang opisina ang sobre.
Incorrect — the office is a destination, not a second ang pivot.
✅ Ibigay mo sa opisina ang sobre bago magtanghali.
Give the envelope to the office before noon.
Adding an English tense ending
❌ Itinapon-ed ni Leo ang sirang kahon kahapon.
Incorrect — itinapon already expresses completed aspect.
✅ Itinapon ni Leo ang sirang kahon kahapon.
Leo threw away the broken box yesterday.
Inventing an i- form from an English gloss
❌ Ilaro mo ang mga bata sa bakuran.
Incorrect for ‘Let the children play in the yard’ — the imagined i- form does not license that meaning.
✅ Hayaan mong maglaro ang mga bata sa bakuran.
Let the children play in the yard.
Key Takeaways
- I- belongs to the guide's benefactive/instrumental voice system; “conveyance voice” describes its frequent theme-moving function.
- The selected pivot may be a conveyed theme, applied content, beneficiary, or instrument-like participant, depending on the lexical verb.
- I- remains across the aspect paradigm while -in- and reduplication mark aspect.
- Actor, pivot, recipient, destination, and beneficiary require different marker frames.
- Learn attested verb families; no single English word predicts where i- is grammatical.
