Sa is Filipino's broad general relator. Depending on the predicate and noun phrase, it can mark a location, destination, time, recipient, source-like reference point, stimulus, or domain. English distributes these relations among at, in, on, to, for, and about, so no one-word translation works.
Sa marks a non-pivot relational phrase. The lexical predicate and context specify the relationship more precisely.
The marker-side analysis appears in sa as oblique and locative marker. This page focuses on the range of relations that the resulting phrase can express.
Major sa relations
| Relation | Example | Likely English rendering |
|---|---|---|
| location | sa silid-aklatan | at/in the library |
| destination | sa palengke | to the market |
| time | sa Lunes | on Monday |
| recipient | sa guro | to the teacher |
| stimulus/reference | takot sa aso | afraid of dogs |
| medium/surface | sa papel | on paper |
Nag-aaral si Pia sa silid-aklatan tuwing hapon.
Pia studies in the library every afternoon.
Pupunta si Pia sa palengke pagkatapos ng klase.
Pia will go to the market after class.
The same sa phrase type receives a location or destination reading from nag-aaral versus motion verb pupunta.
Time and reference
Sa Biyernes ipapadala ng tanggapan ang mga sertipiko.
The office will send the certificates on Friday.
The fronted time phrase sets the frame; contemplated ipapadala selects ang mga sertipiko as the conveyed-theme pivot and retains ng tanggapan as actor.
Mahusay siya sa matematika, pero nahihirapan siya sa kimika.
She is good at mathematics but has difficulty with chemistry.
English changes from at to with. Filipino uses sa because each predicate licenses a domain or stimulus relation.
Recipients and personal markers
Ibinigay ni Omar sa guro ang nawawalang kuwaderno.
Omar gave the missing notebook to the teacher.
With a personal name, use kay, and with coordinated or plural names kina:
Ibinigay ni Omar kay Bb. Reyes ang kuwaderno.
Omar gave the notebook to Ms. Reyes.
Do not treat kay as an unrelated English-style preposition. It is the personal counterpart in the broader sa-series.
Sa with pronouns and demonstratives
Sa-form pronouns are sa akin, sa iyo, sa kaniya, sa amin, sa atin, sa inyo, sa kanila. Deictic forms dito, diyan, doon often replace sa + demonstrative location.
Iwan mo sa akin ang susi; ibabalik ko ito bukas.
Leave the key with me; I will return it tomorrow.
Dito tayo maghintay para hindi tayo mabasa.
Let's wait here so that we do not get wet.
Sa is not always required by English “to”
Tinulungan niya ang kapitbahay na magbuhat ng kahon.
She helped the neighbor carry a box.
English can say gave help to, but Filipino chooses its frame lexically: tumulong in actor voice takes sa kapitbahay, while tinulungan in locative voice selects ang kapitbahay as pivot. Inserting sa after every verb translated with English to produces errors.
Likewise, motion can build a destination into voice morphology or use another lexical relator. Learn a verb together with its normal participant frame.
Lexical selection matters
Many adjectives and predicates conventionally select a sa phrase: galit sa “angry with/at,” takot sa “afraid of,” sanay sa “accustomed to,” interesado sa “interested in,” and sumang-ayon sa “agree with.” This is partly lexical and must be learned from usage; there is no universal English-preposition conversion rule.
Sumang-ayon ang lupon sa mungkahing baguhin ang iskedyul.
The committee agreed to the proposal to change the schedule.
Here sa mungkahi is licensed by sumang-ayon. English agree to a proposal and agree with a person use different prepositions, while Filipino can use sa in both relations and let the complement clarify the reading.
Repeated sa phrases are fully acceptable when each marks a different relation. English style may discourage repeated prepositions, but deleting a required sa can obscure how a participant, place, or time relates to the predicate. Filipino clarity takes priority over avoiding repetition.
Questions and negation
Saang tanggapan mo isinumite ang aplikasyon?
At which office did you submit the application?
Saang is saan + linker -g before tanggapan. Completed isinumite selects ang aplikasyon as the conveyed-theme pivot and keeps actor mo.
Hindi ako sanay sa matinding ingay sa gabi.
I am not accustomed to intense noise at night.
Negation does not remove the relational complement required by sanay.
A short exchange
—Saan tayo magkikita? —Sa harap ng lumang sinehan, sa alas-tres.
—Where shall we meet? —In front of the old cinema, at three.
The first sa belongs to a compound spatial relation; the second marks time. Their English translations differ because the relations differ.
Common Mistakes
❌ Pupunta ako ang ospital mamaya.
Incorrect — a destination is a sa phrase, not an ang pivot here.
✅ Pupunta ako sa ospital mamaya.
I will go to the hospital later.
❌ Ibinigay ko sa Maria ang sobre.
Incorrect — a singular personal name takes kay.
✅ Ibinigay ko kay Maria ang sobre.
I gave the envelope to Maria.
❌ Mahusay siya ng matematika.
Incorrect — mahusay selects a sa relation for the domain.
✅ Mahusay siya sa matematika.
She is good at mathematics.
❌ Sa umalis kami pagkatapos ng tanghalian.
Incorrect English-style use of sa for 'at leaving'; a time clause needs an appropriate linker or conjunction.
✅ Umalis kami pagkatapos ng tanghalian.
We left after lunch.
