Doing something for a beneficiary — the person you go to the trouble for
Lesson 2 ended on a teasing pair: binigyan (I gave Mom something — she received it) versus ibinili (I bought something for Mom — on her behalf). That second idea — acting for someone's benefit — is common enough in Tagalog to earn its own spotlight: benefactive focus, built with the prefix i-.
The system is the one you know. The affix and the ang marker agree; here ang lands on the beneficiary — the person who gains from the action — while the doer and the thing both drop to ng. A fourth spotlight on the same stage.
The i- prefix aims the spotlight at the beneficiary: the one you do the action for. You cook for the family, buy for a friend, fetch water for Grandpa. That "for whom" is the beneficiary, and benefactive i- puts it in the ang spotlight.
Notice the beneficiary need not receive the thing at that moment — the point is that the action is done on their behalf. That's the whole difference from the recipient of Lesson 2.
Benefactive i- sits on the front of the word, and the familiar aspect machinery — the -in- infix and reduplication — works inside, right after the i-. Here is bili → ibili (buy for) in all four aspects:
| Aspect | Form | Meaning |
|---|---|---|
| Infinitive / command | ibili | to buy (it) for someone |
| Completed (past) | ibinili | bought (it) for someone |
| Incompleted (present) | ibinibili | is buying (it) for someone |
| Contemplated (future) | ibibili | will buy (it) for someone |
See how ibinili is just i- + binili (the completed object-focus form you already know). The i- rides in front while the aspect happens on the root. More common benefactive verbs:
| Root → i- | Infinitive | Completed | Incompleted | Contemplated |
|---|---|---|---|---|
| kuha → get for | ikuha | ikinuha | ikinukuha | ikukuha |
| dala → bring for | idala | idinala | idinadala | idadala |
| luto → cook for | iluto | iniluto | iniluluto | iluluto |
Same swap, new target. In benefactive focus the ang spotlight lands on the beneficiary; the doer takes ng, and the thing also takes ng:
For personal names the spotlight marker is si (that's the ang-form for names), and the non-focus doer is ni. So si Nanay / si Lolo are the beneficiaries in focus — the thing bought or fetched stays back in ng.
This is the heart of the lesson. The same shopping trip can be told three ways depending on which role is the news. Watch the affix and the ang-phrase move together:
| Focus | Sentence | ang marks… | Nuance |
|---|---|---|---|
| OF Object (-in) | Binili ko ang gamot. | the thing | "I bought the medicine." |
| LF Locative (-an) | Binigyan ko si Nanay ng gamot. | the recipient | "I gave Mom the medicine." (she receives it) |
| BF Benefactive (i-) | Ibinili ko si Nanay ng gamot. | the beneficiary | "I bought the medicine for Mom." (on her behalf) |
Some roots don't take a bare i- for the benefactive — they use the longer prefix ipag- instead. The meaning is the same ("do X for someone"); it's just the shape the root prefers. Luto is the classic one:
| Aspect | i- form | ipag- form |
|---|---|---|
| Infinitive | iluto | ipagluto |
| Completed | iniluto | ipinagluto |
| Incompleted | iniluluto | ipinagluluto |
| Contemplated | iluluto | ipagluluto |
You don't have to reach for the benefactive affix. Tagalog also lets you keep an ordinary actor- or object-focus verb and tack on para kay / para sa ("for") — the analytic way to name a beneficiary:
| Synthetic (benefactive affix) | Analytic (para kay/sa) |
|---|---|
| Ibinili ko si Nanay ng gamot. | Bumili ako ng gamot para kay Nanay. |
| Iniluto niya ang bata ng pansit. | Nagluto siya ng pansit para sa bata. |
Use para kay + a personal name (para kay Ana, para kay Nanay) and para sa + a common noun or pronoun (para sa bata, para sa iyo). The affix version spotlights the beneficiary; the para version keeps the doer or thing in focus and just adds the "for" phrase on the side. Both are correct — pick the one whose spotlight matches your conversation.
Give the requested aspect (keep the i-):
Fill in ang, si, or ng — in benefactive focus the beneficiary wears the spotlight:
Answer OF (object, -in), LF (locative recipient, -an), or BF (benefactive, i-):
Choose the correct connector for each beneficiary:
Read the intent and answer LF (give-to, -an) or BF (do-for, i-):
You now command four spotlights: actor, object, locative (give-to), and benefactive (do-for). The i- prefix (with its ipag- cousin) puts ang on the beneficiary, and para kay/sa gives you an easy analytic backup. Every one of these is the same ang↔ng machine from Lesson 1, aimed at a different role. Next we shift gears: instead of who is spotlighted, Lesson 4 asks who actually does the work — causative verbs (magpa-/ipa-), for when you have someone else do it.
