English sentences have subjects. Tagalog sentences have a focus — a participant the sentence is about — and the verb changes to announce which one it is. This is the heart of the language, and it is not a variation on anything English does.
One event, five sentences
Take a man buying fish at the market for a child, using money. Every version below describes the same event, and each puts a different participant in focus.
| Tagalog | Focus | Rough English |
|---|---|---|
| Bumili ang lalaki ng isda. | actor | The man bought fish. |
| Binili ng lalaki ang isda. | object | The fish was bought by the man. |
| Binilhan ng lalaki ang palengke. | location | The market is where he bought it. |
| Ibinili ng lalaki ang bata. | beneficiary | The child is who he bought it for. |
| Ipinambili ng lalaki ang pera. | instrument | The money is what he bought it with. |
The verb root is bili throughout. The affix changes — -um-, -in, -an, i-, ipang- — and the marker ang moves to whichever noun is in focus.
This is not the passive voice. English passives demote the actor and often drop it. Tagalog focus does not demote anyone — all participants stay present and fully expressed. It is closer to choosing what the sentence is about, and object focus is the more common choice in ordinary Tagalog, not a marked alternative.
The markers
| Marker | Job | For names |
|---|---|---|
| ang | the focused participant | si |
| ng | non-focused actor or object | ni |
| sa | location, direction, indirect | kay |
Ng is pronounced nang and is one of the first things to get used to. Personal names take the parallel set: si Maria, ni Maria, kay Maria.
The verb affixes
| Focus | Affix | Example from sulat (write) |
|---|---|---|
| Actor | -um-, mag- | sumulat — to write |
| Object | -in | sulatin — to write it |
| Location | -an | sulatan — to write on it |
| Beneficiary | i- | isulat — to write for/down |
Aspect is marked by reduplication and infixing rather than by tense:
| Form | Aspect | Meaning |
|---|---|---|
| sumulat | completed | wrote |
| sumusulat | ongoing | is writing |
| susulat | not begun | will write |
Note that Tagalog marks completion rather than time, so the same form covers "wrote" and "has written" — closer to Slavic aspect than to English tense.
Word order is predicate-first
The verb or predicate normally opens the sentence, with the ang phrase following:
| Tagalog | Literally | English |
|---|---|---|
| Maganda ang bahay. | Beautiful the house | The house is beautiful. |
| Guro si Ana. | Teacher Ana | Ana is a teacher. |
There is no verb "to be" in these sentences — the predicate simply comes first.
The vocabulary is generous
Over three centuries of Spanish rule left thousands of loanwords, and English borrowing is heavy and ongoing.
| Tagalog | From | Meaning |
|---|---|---|
| mesa | Spanish | table |
| kabayo | Spanish caballo | horse |
| kusina | Spanish cocina | kitchen |
| eskwelahan | Spanish escuela | school |
Numbers are commonly borrowed too — Spanish numerals for prices and time, native ones for counting.
How to approach it
Learn actor focus and object focus thoroughly before touching the others; they cover most ordinary speech. Then train the habit of asking what the sentence is about before choosing the verb form, rather than translating an English subject across. That reframing is the whole difficulty, and once it lands the affixes are just a table.

Are Tagalog and Filipino the same language?
Filipino is the national standard, based on Tagalog and officially open to vocabulary from other Philippine languages and from English and Spanish. In everyday practice the terms are used interchangeably, and material labelled either way teaches essentially the same language.
What is the focus system?
A way of marking which participant in the event the sentence is about. The verb takes an affix showing whether the focus is the actor, the object, the location, the beneficiary or the instrument, and the focused noun gets the marker ang. Changing focus changes the verb, not the word order.
Is Tagalog hard for English speakers?
The vocabulary is friendly — there are thousands of Spanish loanwords and heavy English borrowing. The focus system is the genuine difficulty, because it requires thinking about sentences in a way English never asks for.
