Sa-Form Pronouns | Filipino Grammar

The long pronoun forms akin, iyo, kaniya, atin, amin, inyo, and kanila appear after sa to express recipients, destinations, locations, beneficiaries, and other oblique relationships. The same forms also serve as independent possessives: akin can mean “mine,” while linked aking can mean “my” before a noun.

These are not just longer versions of ko, mo, and niya. A short ng-form is an enclitic; a sa-form is a full phrase that can be contrasted, coordinated, or placed at the front of a clause. Keeping those structures separate prevents errors such as sa ko and para natin.

The long forms and their three shapes

Person	After sa	Independent possessive	Before a noun
First singular	sa akin	akin	aking
Second singular	sa iyo	iyo	iyong
Third singular	sa kaniya	kaniya	kaniyang
First plural, inclusive	sa atin	atin	ating
First plural, exclusive	sa amin	amin	aming
Second plural/respectful	sa inyo	inyo	inyong
Third plural	sa kanila	kanila	kanilang

The linked forms follow the ordinary linker rule: a base ending in a vowel takes -ng, while kanila likewise becomes kanilang. Kaniya is the careful standard spelling used on this page. Kanya and kanyang are widespread (informal) spellings, especially in messages and casual publications, but learners should control kaniya/kaniyang in standard writing.

Pakibigay sa akin ang resibo bago ka umalis.

Please give me the receipt before you leave.

Hindi para sa amin ang mesang iyon; para sa inyo iyon.

That table isn't for us; it's for you.

In the second example, amin excludes the people being addressed, while inyo refers to those people. If the speaker meant a shared group that included the addressee, the form would be atin.

After sa: recipient, endpoint, location, and beneficiary

The marker sa is a general relator rather than a single equivalent of English “to,” “at,” or “for.” The predicate and context determine the relationship. With a person, sa kaniya may identify a recipient; with a group, sa kanila can identify a destination or the group’s place.

Ibinigay ni Lito ang susi sa bagong bantay.

Lito gave the key to the new guard.

Ibinigay ni Lito ang susi sa kaniya.

Lito gave the key to him/her.

This is a controlled substitution: sa bagong bantay → sa kaniya. The full prepositional phrase is replaced as a unit. Sa niya is impossible in standard Filipino because niya belongs to the short ng-form series.

The same substitution works with a plural human phrase:

Magpapadala kami ng kopya sa mga tagapamahala ngayong hapon.

We will send a copy to the managers this afternoon.

Magpapadala kami ng kopya sa kanila ngayong hapon.

We will send them a copy this afternoon.

With personal names, Filipino normally uses kay for one person and kina for more than one, but the pronoun replacement still uses sa:

Dadaan ako kina Rosa at Ben pagkatapos ng trabaho.

I'll stop by Rosa and Ben's place after work.

Dadaan ako sa kanila pagkatapos ng trabaho.

I'll stop by their place after work.

Here sa kanila is naturally understood as “to/at their place.” The sense comes from dadaan and the shared context, not from a special locative meaning built into kanila.

Voice can change a sa-form into an ang-form

A recipient is not permanently assigned to the sa-series. Under patient voice, the transferred item may be the pivot and the recipient remains in a sa-phrase. Under locative/recipient voice, the recipient becomes the pivot and therefore takes an ang-form.

Ibinigay ko sa kaniya ang gamot pagkatapos kumain.

I gave him/her the medicine after the meal.

Binigyan ko siya ng gamot pagkatapos kumain.

I gave him/her medicine after the meal.

Both sentences are natural, but they organize the event differently. In the first, ang gamot is the patient pivot and sa kaniya is the recipient. In the second, siya is the recipient pivot. English uses “him/her” in both, so English object form cannot choose the Filipino series for you.

💡

A recipient often appears as sa kaniya or sa kanila, but voice may promote that recipient to the pivot as siya or sila. Identify the pivot before choosing a pronoun series.

Long possessives: mine, yours, and theirs

Without sa, a long form can stand as a possessive predicate. Predicate-first order is neutral:

Akin ang kuwadernong may asul na pabalat.

The notebook with the blue cover is mine.

Kanila ang bahay na may berdeng tarangkahan.

The house with the green gate is theirs.

This construction contrasts or identifies ownership. For an ordinary noun phrase meaning “my notebook,” the compact post-noun form kuwaderno ko is more frequent in everyday speech. A linked long form can precede the noun:

Dinala ko ang aking kuwaderno para sa pulong.

I brought my notebook to the meeting.

Pakinggan natin ang kanilang mungkahi bago tayo magpasya.

Let's listen to their suggestion before we decide.

Pre-noun aking, iyong, kaniyang, ating, aming, inyong, and kanilang are standard. They are especially common when the noun phrase is deliberate, contrastive, written, or part of a set expression. In casual conversation, a post-noun short possessive—kuwaderno ko, mungkahi nila—is often lighter. That is a preference, not a claim that the linked forms are archaic.

Compare the three structures directly:

Structure	Example	Typical job
sa + long form	sa akin	to/at/for me, as licensed by context
bare long form	akin	mine; possessive predicate
linked long form + noun	aking kuwaderno	my notebook
noun + short ng-form	kuwaderno ko	my notebook, especially common in conversation

For a fuller comparison, see short versus long possessives.

Full phrases, contrast, and questions

Unlike the compact ng-forms, sa-phrases can be placed first to establish a contrast. A short clitic may then appear after that initial phrase.

Sa iyo ko ipinadala ang orihinal; sa kanila ang kopya.

I sent the original to you; the copy went to them.

The interrogative counterpart is kanino “to/for/at whom?” A natural exchange makes the contrast clear:

Kanino mo ipinadala ang mga larawan?

Who did you send the photos to?

Sa kanila ko ipinadala kahapon, pero hindi pa nila nakikita.

I sent the photos to them yesterday, but they haven't seen them yet.

English repeats “them” for both the photos and the people. Filipino leaves the already known photos unexpressed in the answer, uses sa kanila for the recipients, and uses nila for the non-pivot experiencers of nakikita.

An entire sa-phrase can also be omitted when its relationship is irrelevant or understood:

Naipadala ko na ang mga larawan.

I've already sent the photos.

What cannot remain is a bare sa without its complement. Omission removes the whole phrase; it does not turn sa akin into sa or replace it with ko.

💡

Use the long series after sa and related expressions: sa akin, para sa iyo, mula sa kaniya, tungkol sa atin. Use ko, mo, and niya only where an ng-form clitic belongs.

Common Mistakes

Combining sa with a short ng-form

❌ Ipadala mo sa ko ang bagong iskedyul.

Incorrect — ko cannot serve as the complement of sa.

✅ Ipadala mo sa akin ang bagong iskedyul.

Send me the new schedule.

Omitting sa after para

❌ Para natin ang libreng seminar na ito.

Incorrect for 'for us' — para requires a sa-phrase here.

✅ Para sa atin ang libreng seminar na ito.

This free seminar is for all of us, including you.

Using a bare long form directly before a noun

❌ Naiwan sa opisina ang akin payong.

Incorrect — the pre-noun possessive needs the linker -ng.

✅ Naiwan sa opisina ang aking payong.

My umbrella was left at the office.

Dropping sa before a recipient

❌ Ipinadala ko kaniya ang kumpletong detalye.

Incorrect in this patient-voice structure — the recipient needs sa kaniya.

✅ Ipinadala ko sa kaniya ang kumpletong detalye.

I sent him/her the complete details.

Key Takeaways

After sa, use akin, iyo, kaniya, atin, amin, inyo, kanila, never ko, mo, niya, and the other short ng-forms.
The same long forms can be possessive predicates: Akin ang kuwaderno “The notebook is mine.”
Before a noun, attach the linker: aking kuwaderno, iyong susi, kanilang mungkahi.
A participant may alternate between a sa-form and an ang-form when voice changes its relationship to the pivot.
Atin includes the addressee; amin excludes the addressee.
