The ma- stative and ability: Incompleted-Aspect Formation | Filipino Grammar

The incompleted member of a verbal ma- family normally begins with na- and repeats the first consonant–vowel sequence of the base: matulog → natutulog, matakot → natatakot, mabasa → nababasa, makita → nakikita. It presents a state or event as continuing, recurring, or generally available.

English translations vary widely: “is sleeping,” “is afraid,” “can read,” “sees,” and “keeps breaking” can all correspond to this morphology. The shared feature is an internally open state, event, capacity, or pattern—not English present tense.

Formation

Basic form	Base copied	Incompleted structure	Surface form
matulog	tu-	na + tu + tulog	natutulog
matakot	ta-	na + ta + takot	natatakot
matuwa	tu-	na + tu + tuwa	natutuwa
mabasa	ba-	na + ba + basa	nababasa
makita	ki-	na + ki + kita	nakikita
mabasag	ba-	na + ba + basag	nababasag

The analytical spaces are not ordinary spelling. Write natutulog, natatakot, natutuwa, nababasa, nakikita, and nababasag as single words.

The prefix is attached to the relevant base, which may already contain lexical morphology. Surface changes must be learned: marinig/narinig/naririnig/maririnig “hear” shows the established d/r alternation associated with the base dinig/rinig, not a form mechanically recoverable by copying written letters alone.

For the cross-family semantics, see incompleted aspect.

An ongoing state or event

Natutulog pa ang pasyente, kaya mamaya na tayo bumalik.

The patient is still sleeping, so let's return later.

Natutuwa si Lola kapag sabay-sabay kaming kumakain.

Grandmother is happy when we all eat together.

The sleeper and experiencer are pivots. Pa presents the sleeping as continuing; the kapag clause makes the pleasure recurrent. Neither participant is necessarily a deliberate agent.

Past time is equally possible:

Natutulog ang mga bata nang dumating ang kanilang ama kagabi.

The children were sleeping when their father arrived last night.

Kagabi and completed dumating create a past frame. Natutulog remains incompleted because the viewpoint lies inside the sleeping event. It is not a present-tense form.

💡

Use context to choose an English tense. Filipino natutulog can mean “is sleeping,” “was sleeping,” or “sleeps habitually.”

Ongoing perception and general ability

With potential ma-, the incompleted form often describes continuing access, perception, or capacity rather than an action visibly in progress.

Nakikita ko ang ilog mula sa bintana ng silid.

I can see the river from the room's window.

Nababasa ni Lino ang maliliit na letra kahit walang salamin.

Lino can read the small letters even without glasses.

The river and letters are pivots; perceiver ko and reader ni Lino are non-pivots. An English speaker may expect I or Lino to take ako/si, but that would switch the Filipino alignment.

The incompleted form can also express repeated success:

Nabubuksan ko ang lumang kabinet kapag ginagamit ko ang maliit na susi.

I can open the old cabinet when I use the small key.

This does not mean that an opening is unfolding at every moment. It states a repeatable capacity under the given condition. The full form nabubuksan contains potential na-, reduplicated bu-, and the lexical suffix -an.

💡

Potential incompleted forms often correspond to English can, not only be + -ing. Capacity is an open possibility across occasions.

Recurring spontaneous or accidental results

Nababasag ang manipis na tasa kapag binubuhusan ng kumukulong tubig.

The thin cup breaks when boiling water is poured into it.

The cup is an inanimate pivot. Nababasag presents a recurring susceptibility or result, with no deliberate actor in the main clause. If an accidental causer is expressed, that participant takes an ng/ni form.

Laging nawawala ang susi ni Enzo kapag nagmamadali siya.

Enzo's key always goes missing when he is in a hurry.

This pattern presents repeated nonvolitional loss without adding a causer to the verb's core frame. A speaker can instead choose a construction that explicitly presents Enzo as losing the key; such choices reflect lexical and discourse preferences, not a freely applicable formula.

Controlled comparison with completed aspect

Nakita ni Mara ang tore nang humawi ang ulap.

Mara saw the tower when the clouds parted.

Nakikita ni Mara ang tore kapag malinaw ang kalangitan.

Mara can see the tower when the sky is clear.

Completed nakita presents one bounded perception. Incompleted nakikita presents recurring or continuing visual access. Both select ang tore as pivot and mark the perceiver with ni Mara.

Negation, questions, and a short exchange

Hindi naririnig ni Pia ang anunsiyo dahil maingay sa pasilyo.

Pia cannot hear the announcement because the hallway is noisy.

Negation scopes over current perceptual access; naririnig retains its incompleted form.

—Nababasa mo ba ang numero sa karatula? —Hindi pa; natatakpan pa ng sanga ang huling bilang.

—Can you read the number on the sign? —Not yet; a branch is still covering the final digit.

The question uses nababasa for present ability. The reply uses hindi pa because visibility may improve; natatakpan describes the continuing covered state.

Lexical restrictions and alternatives

The formation rule operates only inside an attested family. A root is a family of constructions, and one citation form hides its derivational system. Current ability may also be expressed with kaya: Kaya kong basahin ang maliliit na letra. That construction makes capacity explicit, while Nababasa ko ang maliliit na letra packages the text as the potential pivot. Both are standard, but their grammar is not interchangeable word for word.

Property-word reduplication is separate. Malalaki relates to plural-associated malaki “large,” whereas natutuwa is an aspect-bearing verb. Similar repeated syllables do not imply the same grammatical process.

Common Mistakes

Retaining both ma- and na-

❌ Namatutulog ang bata sa sopa ngayon.

Incorrect — begun-event na- replaces ma-; the two prefixes are not stacked.

✅ Natutulog ang bata sa sopa ngayon.

The child is sleeping on the sofa now.

Copying the prefix instead of the base

❌ Nananakita ko ang ilog mula rito.

Incorrect — nakikita repeats ki- from the base kita, not na- from the prefix.

✅ Nakikita ko ang ilog mula rito.

I can see the river from here.

Giving the reader pivot marking

❌ Nababasa ako ang tala kahit malabo ang tinta.

Incorrect — in this potential frame, the text is pivot and the reader uses ko.

✅ Nababasa ko ang tala kahit malabo ang tinta.

I can read the note even though the ink is faint.

Treating incompleted aspect as present only

❌ Natulog ang mga bata nang dumating ako kagabi.

Wrong for the intended background meaning ‘were sleeping’; natulog presents a bounded sleeping event.

✅ Natutulog ang mga bata nang dumating ako kagabi.

The children were sleeping when I arrived last night.

Key Takeaways

Incompleted verbal ma- uses na- plus reduplication of the base's first consonant–vowel sequence.
Stative readings include ongoing and recurring states or events.
Potential readings include continuing perception, general ability, and repeatable opportunity.
Patient-potential forms select the perceived or affected entity as pivot, not the English subject-like experiencer.
Learn actual surface forms and lexical frames; reduplication alone cannot predict meaning or voice.
