ter- versus di- in Malaysian Malay

Both ter- and di- can put a patient or result in the foreground, so English translations sometimes make both look like passives. Their viewpoints differ. Di- normally presents an event done to the patient, with a deliberate or at least identifiable actor available in the discourse. Ter- commonly presents an accidental event, an uncontrolled occurrence, a resultant state, or—especially under negation—what can or cannot be done.

The most useful diagnostic is not past time. Ask Does the clause report an actor’s event, or does it foreground lack of control and the endpoint now visible? Pintu dibuka reports an opening event; pintu terbuka presents the door as open or as having come open.

The core contrast

Di- presents a passive event

The di- passive promotes the affected participant as the clause topic or subject while the actor is backgrounded, omitted, or expressed after the verb, commonly with oleh in careful prose. It answers questions such as “What happened to the application?” or “Who opened the gate?”

The separate di- Passive overview develops its full argument structure and discourse behavior.

The actor need not be intentional in the philosophical sense—Pokok itu ditiup angin kencang “The tree was buffeted by strong wind” still has a causal participant. What matters is that the clause is structured as an event affecting the patient. Di- does not itself mean past; sedang diproses is ongoing and akan diumumkan is future.

Ter- presents accident or lack of control

With many action roots, ter- shows that the event happened unintentionally, unexpectedly, or beyond the participant’s control. Malay often keeps the experiencer as subject in such clauses.

The prefix is not a magical “accident” label with every root. Many ter- words are lexicalized, and the same form may favor state, perception, or potential. Learn the productive contrast together with the usage of each frequent verb.

Ter- foregrounds the resulting state

With change-of-state roots, ter- often presents the endpoint as holding, without profiling a deliberate actor. This produces the classic door contrast:

In pintu terbuka, the important information is the state visible now. The sentence does not commit to whether someone deliberately opened it, the wind pushed it, or it was left open. In pintu dibuka, the grammar construes an opening event; the actor can be supplied.

Other result predicates similarly report what is present or recorded:

These are not ordinary past passives. They describe an available result. Compare syarat itu dicatat oleh peguam “the condition was recorded by the lawyer,” which reports the act of recording.

Perception: what becomes available to the senses

Forms such as terdengar foreground the fact that a sound reaches perception, often without deliberate listening. The corresponding di- form describes an act performed on an object.

Compare didengar, which is an eventive passive of mendengar:

English often translates both with a passive involving “heard,” but terdengar emphasizes auditory availability or unintended perception, whereas didengar reports the panel’s listening event.

Potential and inability under negation

A productive ter- reading concerns whether an action is achievable. It is especially clear with tidak, where the result is “cannot be X-ed” rather than merely “was not X-ed.”

Contrast plain di- negation:

Tidak dibaca denies that a reading event occurred. Tidak terbaca says that reading was not possible or that the writing fails to yield a readable result. This difference is one of the clearest tests between the two prefixes.

Positive potential readings exist in context—masih terbaca “still readable”—but a bare positive ter- form may be ambiguous with accident or result. Negation, degree expressions, and context make the potential meaning easier to identify.

Agent expression and control

The di- passive comfortably permits an actor:

With a ter- result, adding oleh often pushes the clause toward a potential reading or sounds unnecessarily heavy. To report a deliberate actor, choose di-. To say that the wind caused an uncontrolled result, a separate causal phrase is often clearer:

Control is a tendency, not a universal biography of the event. A deliberately created state can later be described with ter- because the current state, not the original intention, is in focus: after someone arranges books, Buku-buku itu tersusun rapi di atas rak means “The books are neatly arranged on the shelf.”

A practical decision path

1. If you are reporting what an actor did to a patient, choose di-.
2. If the event was accidental or escaped control, consider ter-.
3. If the clause describes a visible, recorded, open, arranged, or perceptible result, consider ter-.
4. If tidak means “cannot be” rather than “was not,” use the potential ter- pattern.
5. Check the individual word: lexicalized ter- forms do not all allow every reading.

Common Mistakes

1. Calling both forms ordinary past passives

2. Using di- for inability

3. Adding an actor to a result-state clause

4. Treating every ter- form as accidental

Key Takeaways

Use di- to present an event affecting a patient, especially when an actor matters. Use ter- for accidental or uncontrolled events, salient result states, perceptual availability, and potential—most clearly tidak terbaca “cannot be read.” The contrast is about control and viewpoint, not about two interchangeable ways to mark past passive voice.
