The root aral covers studying and learning, but its derived forms also name a lesson, a student, and a sustained examination of a topic. English uses “study” across several syntactic patterns; Filipino divides those patterns among mag-aral, aralin, and pag-aralan, each with its own voice and participant marking.
The core family
All forms in this table are (neutral) unless a later note says otherwise. Aspect describes the event's internal contour, not a fixed past, present, or future tense.
| Family and function | Basic | Completed | Incompleted | Contemplated | Typical frame |
|---|---|---|---|---|---|
| Actor voice: study, attend to learning | mag-aral | nag-aral | nag-aaral | mag-aaral | ang learner + ng material / sa institution |
| Patient voice: learn or study selected material | aralin | inaral | inaaral | aaralin | ng/ni learner + ang material |
| Patient voice: investigate or study a subject in depth | pag-aralan | pinag-aralan | pinag-aaralan | pag-aaralan | ng/ni investigator + ang topic, problem, or evidence |
The difference between aralin and pag-aralan is partly lexical, not a perfectly mechanical rule. Aralin readily refers to assigned material or something to be learned; pag-aralan often suggests examining, analyzing, or giving sustained attention to a topic or proposal. In many contexts both are possible, but the second can sound more investigative.
Nag-aaral si Jessa ng matematika tuwing gabi.
Jessa studies mathematics every evening. (incompleted habitual actor voice; neutral)
Nag-aral kami sa silid-aklatan hanggang magsara ito.
We studied at the library until it closed. (completed actor voice; neutral)
In the first example, si Jessa is pivot and ng matematika supplies the field of study. In the second, sa silid-aklatan is a location, not a direct object. English word order alone cannot predict these markers.
Actor voice versus patient voice
Voice selects what the clause organizes as pivot. Compare the same learner and chapter:
Nag-aral si Emil ng ikatlong kabanata pagkatapos ng hapunan.
Emil studied the third chapter after dinner. (actor voice; neutral)
Inaral ni Emil ang ikatlong kabanata pagkatapos ng hapunan.
Emil studied the third chapter after dinner. (patient voice; neutral)
The actor-voice clause selects si Emil and presents the material with ng. The patient-voice clause selects ang ikatlong kabanata and marks the learner with ni Emil. Both can refer to the same identifiable third chapter: ng is not an article meaning “a.” This is a discourse choice, not a difference between English active and passive. See patient voice for the broader system.
Aralin versus pag-aralan
Aralin is natural for a lesson, chapter, skill, or body of facts treated as learnable material. Pag-aralan is especially common with proposals, causes, evidence, systems, and problems that must be examined before a decision.
Aaralin ng mga bata ang bagong awit para sa programa.
The children will learn the new song for the program. (contemplated patient voice; neutral)
Pinag-aaralan pa ng konseho ang epekto ng bagong ruta sa mga pasahero.
The council is still studying the effect of the new route on passengers. (incompleted patient voice; formal/neutral)
The council example does not mean that members are memorizing a lesson. Pinag-aaralan presents an ongoing inquiry. In everyday speech, a family can similarly pag-aralan ang mga pagpipilian before buying something.
Pag-aaralan muna namin ang tatlong alok bago kami pumili.
We will examine the three offers first before we choose. (contemplated patient voice; neutral)
There is genuine overlap. Aralin natin ang dahilan can mean “Let us learn/examine the reason,” while Pag-aralan natin ang dahilan more strongly invites investigation. No one English gloss encodes that nuance every time.
Nouns built from aral
Bare aral can mean a lesson, teaching, or moral: ang aral ng kuwento “the lesson of the story.” Pag-aaral names studying, research, or a study, depending on context. Mag-aaral can be either the contemplated verb “will study” or the noun “student.” Syntax and surrounding words resolve the ambiguity.
The established expression may pinag-aralan means “educated” or “having had schooling.” Its negative counterpart walang pinag-aralan can sound disparaging when applied to a person, so it should not be used as a neutral substitute for a precise description of someone's educational background.
Mahalaga ang aral ng kuwento, pero masyadong mahaba ang paliwanag.
The lesson of the story is important, but the explanation is too long. (noun use; neutral)
Ang mga mag-aaral ay mag-aaral sa bahay bukas dahil sarado ang paaralan.
The students will study at home tomorrow because the school is closed. (formal ay-clause followed by contemplated verb)
The first mag-aaral follows plural marker mga and is a noun. The second is the predicate and is a contemplated verb. The sentence is intentionally formal; ordinary speech more often uses predicate-first order: Mag-aaral sa bahay bukas ang mga mag-aaral.
The activity noun pag-aaral follows a partly lexicalized pattern discussed under nominalization with pag-. Do not derive every noun mechanically from a verb form.
Questions, negation, and actual interaction
Hindi pa namin pinag-aralan ang bahaging tungkol sa buwis.
We have not studied the section about tax yet. (negative patient voice; neutral)
Exclusive namin marks the learner group as non-pivot; ang bahagi is pivot. Hindi pa means the study has not occurred up to the relevant point but remains expected.
—Ano ang inaaral mo ngayon? —Kasaysayan ng Timog-Silangang Asya, pero pagrerepaso lang ito.
—What are you studying now? —Southeast Asian history, but this is only review. (neutral conversation)
The interrogative ano fills the selected-material slot of patient-voice inaaral. English asks “What are you studying?” without revealing voice; Filipino morphology and mo do.
Collocations, restrictions, and register
Common combinations include mag-aral nang mabuti “study well,” mag-aral para sa pagsusulit “study for the exam,” aralin ang leksiyon, pag-aralan ang problema, larangan ng pag-aaral, and takdang-aralin “homework.” Write mag-aral, nag-aral, nag-aaral, and mag-aaral with a hyphen because the root begins with a vowel.
Magpakadalubhasa or more specific expressions may suit advanced specialization; mag-aral itself remains neutral at every education level. English “learn” is not always aral: learning a fact may use malaman, and learning how to do something may use matutong + verb. The root family should not be forced into every English sentence containing “learn.”
Common Mistakes
Treating the selected material like an English object after actor voice
❌ Nag-aaral si Rafi ang mga bagong termino.
Incorrect — actor-voice nag-aaral selects Rafi; the study material cannot also take ang in this frame.
✅ Nag-aaral si Rafi ng mga bagong termino.
Rafi is studying some new terms. (actor voice; neutral)
If the terms are the selected pivot, use Inaaral ni Rafi ang mga bagong termino instead.
Keeping an ang-form actor with patient voice
❌ Pinag-aaralan si Rafi ang bagong patakaran.
Incorrect — pinag-aaralan is patient voice, so the investigator takes ni and the policy takes ang.
✅ Pinag-aaralan ni Rafi ang bagong patakaran.
Rafi is examining the new policy. (patient voice; neutral)
Omitting the hyphen in vowel-initial forms
❌ Magaaral kami pagkatapos ng trabaho.
Incorrect standard spelling — mag- before vowel-initial aral requires a hyphen.
✅ Mag-aaral kami pagkatapos ng trabaho.
We will study after work. (contemplated actor voice; neutral)
The hyphen makes the affix boundary visible; it is not optional decoration.
Translating every English “learn” with aral
❌ Inaral ko kahapon na kanselado ang biyahe.
Unnatural for the intended discovery — inaral suggests deliberate study, not simply finding out a fact.
✅ Nalaman ko kahapon na kanselado ang biyahe.
I learned yesterday that the trip was canceled. (finding out a fact; neutral)
Key Takeaways
- Use mag-aral when the learner is pivot and aralin/pag-aralan when the material or topic is pivot.
- Aralin favors learnable material; pag-aralan often adds sustained examination, though overlap is real.
- Read mag-aaral from its syntax: it can mean “student” or “will study.”
- Preserve the hyphen in all mag-/nag- + aral forms and keep aspect distinct from English tense.
