Filipino dictionaries do not all cite verbs in the same way. One may organize an entry under the bare root bili, while a learner's dictionary may list actor-voice bumili “to buy” and patient-voice bilhin “to buy the selected thing” separately. Both practices are useful, but neither single headword represents the entire family.
A good personal citation form records enough information to reconstruct actual usage: the root, voice family, infinitive/basic form, aspect forms, participant frame, and lexical meaning. Writing only “buy = bili” hides too much.
Three things called a “base form”
| Entry type | Example | What it tells you | What it hides |
|---|---|---|---|
| bare root | bili | where related words are grouped | voice, aspect, and clause frame |
| infinitive/basic actor voice | bumili | one actor-voice family | patient and other voices |
| infinitive/basic patient voice | bilhin | one patient-voice family and surface alternation | actor voice and the rest of the paradigm |
| completed surface form | binili | an attested completed patient-voice form | which citation convention the dictionary uses |
Terms vary across reference works. Infinitive, basic form, and neutral form may label the aspect-neutral member used in commands and many dependent environments. This Filipino “infinitive” is not simply English to + verb: it is already marked for voice and carries a participant pattern.
Root entries reveal families
Start from a root when you want to survey related constructions.
Bumili si Lani ng isda bago magsara ang palengke.
Lani bought fish before the market closed.
Bilhin mo ang isdang sariwa pa ang mata.
Buy the fish whose eyes are still fresh.
Binili ni Lani ang isda para sa hapunan.
Lani bought the fish for dinner.
All three forms belong under bili, but they are not interchangeable. Bumili is actor voice; bilhin/binili are patient voice in infinitive/basic and completed use. The actual surface form bilhin also shows why merely appending letters to bili is unsafe.
An infinitive-style citation preserves voice
For practical vocabulary study, an affixed citation form is often more useful than a root alone:
| Root | Voice/family | Useful citation form | Typical frame |
|---|---|---|---|
| kain | actor voice, -um- | kumain | kumain ang/si actor ng food |
| luto | actor voice, mag- | magluto | magluto ang/si actor ng food |
| basa | patient voice, -in | basahin | basahin ng/ni actor ang text |
| sulat | locative voice, -an | sulatan | sulatan ng/ni writer ang recipient |
| bigay | conveyance/instrumental voice, i- | ibigay | ibigay ng/ni giver ang item sa recipient |
The frame prevents a frequent mistake: memorizing basahin as merely “read” and then combining it with actor-voice markers. It tells you that the selected text is the ang-marked pivot.
Basahin mo ang mensahe bago ka sumagot.
Read the message before you reply.
Ibigay mo kay Ruben ang ekstrang susi.
Give Ruben the spare key.
Both are positive commands using infinitive/basic forms, but basahin selects a patient pivot and ibigay selects the conveyed item as pivot. Citation forms retain these differences.
The -um- ambiguity: citation and completed forms coincide
For many -um- verbs, the infinitive/basic form and completed aspect have the same spelling.
Kumain ka muna bago bumiyahe.
Eat first before traveling.
Kumain si Nilo bago bumiyahe kahapon.
Nilo ate before traveling yesterday.
The first kumain is directive and aspect-neutral/basic in this analysis. The second is completed. A dictionary headword kumain therefore does not mean the form is always past or always nonfinite. Syntax and context select the use.
The ambiguity is less hidden in a mag- family: citation magluto contrasts visibly with completed nagluto, incompleted nagluluto, and contemplated magluluto.
How to record a working lexical entry
For an unfamiliar verb, record at least these fields:
- root and actual surface changes;
- citation form and voice label;
- completed, incompleted, and contemplated forms;
- a natural marker frame;
- one specific English gloss in that frame;
- any lexical or register restriction.
For example: basa — basahin (patient voice): binasa, binabasa, babasahin; actor ni/ng, text ang; “read the selected text.” A separate entry would record actor-voice bumasa if relevant to the intended usage. This is longer than a bilingual word pair, but it prevents multiple downstream errors.
One root may need several citations
The root punta supports forms with different alignments and conventional meanings.
Pumunta si Carla sa klinika pagkatapos ng tanghalian.
Carla went to the clinic after lunch.
Puntahan mo si Carla sa klinika bago mag-alas-singko.
Go see Carla at the clinic before five o'clock.
Actor-voice pumunta presents the mover as pivot and marks the destination with sa. Puntahan selects the person or destination approached as pivot. Calling both simply “go” loses a real difference in valency and discourse organization.
Some roots allow -um- and mag- actor-voice forms with distinct lexical meanings or preferences. No dictionary policy can make those contrasts fully predictable. Store each attested verb family separately.
Looking up an inflected form
When you encounter nagluluto, identify likely pieces: nag- signals a mag- actor-voice family in incompleted aspect, lu- is repeated, and luto is the root. Search both the surface word and the root if the dictionary permits it. Do not assume every initial nag- or internal repeated syllable can be stripped mechanically; lexicalized forms and phonological alternations require confirmation.
—Ano ang anyong hahanapin ko sa diksiyonaryo? —Hanapin mo ang luto at magluto, hindi lang ang nagluluto.
—What form should I look for in the dictionary? —Look for luto and magluto, not only nagluluto.
The exchange is metalinguistic but natural in a study setting. It illustrates the two complementary search routes: root and citation form.
For a systematic grid, see verb paradigms as aspect-and-voice families.
Register and dictionary variation
Root-based dictionaries are efficient for morphological analysis, while learner dictionaries often repeat affixed headwords for accessibility. Some sources label the neutral form “infinitive,” others “basic,” and traditional materials may use different voice or pokus terminology. This is terminological variation, not evidence that speakers use different verbs.
Ordinary contemporary Filipino does not announce a citation form in conversation. The choice matters in reference works, word lists, and teaching (academic). Always read the dictionary's front matter before comparing labels across sources.
Common Mistakes
Treating an inflected surface word as the root
❌ Nagluluto ang ugat ng pandiwang ito.
Incorrect — nagluluto is an incompleted actor-voice word, not the root.
✅ Luto ang ugat, at magluto ang isang anyong pansipi.
Luto is the root, and magluto is one citation form.
Using a bare root as an independent projected event
❌ Luto ako ng agahan bukas.
Incorrect for 'I will cook breakfast tomorrow' — bare luto does not express the required actor-voice contemplated predicate.
✅ Magluluto ako ng agahan bukas.
I will cook breakfast tomorrow.
Citing a completed mag- form as the neutral headword
❌ Nagluto ang anyong pansipi para sa pandiwang ito.
Incorrect under the infinitive/basic citation convention — nagluto is completed.
✅ Magluto ang anyong pansipi para sa pamilyang ito.
Magluto is the citation form for this actor-voice family.
Assuming one citation covers every voice
❌ Bumili mo ang pulang payong.
Incorrect — actor-voice bumili cannot take this patient-voice command frame.
✅ Bilhin mo ang pulang payong.
Buy the red umbrella.
Key Takeaways
- Dictionaries may cite a root, an infinitive/basic form, or a surface derivative; check their conventions.
- A root groups relatives, while an affixed citation identifies one voice family.
- Record aspect principal parts and a participant-marker frame with every useful citation.
- -Um- infinitive/basic and completed forms may coincide in spelling.
- One root can require multiple citation entries because its voice families differ in valency or lexical meaning.
