Mampu says that a person, group, or institution has enough strength, skill, resilience, money, or resources for an action. Dia mampu membayar means that payment lies within the person's capacity—not that someone has granted permission and not necessarily that the payment has already occurred.
English can covers capacity, permission, opportunity, and situational possibility. Malaysian Malay divides that territory among mampu, boleh, dapat, sempat, and fuller expressions. The defining question for mampu is whether the subject has the underlying resources to meet a demand.
Physical capacity
Use mampu + verb phrase when the subject has the physical strength or endurance needed for an action.
Walaupun mendaki perlahan-lahan, datuk masih mampu sampai ke pondok rehat itu.
Although he climbed slowly, Grandfather was still capable of reaching that rest shelter.
Selepas terjatuh, dia tidak mampu berdiri tanpa bantuan.
After falling, she was unable to stand without assistance.
The second sentence contains the required pattern tidak mampu berdiri. It evaluates the person's capacity after the fall. It does not say that standing was forbidden.
Physical capacity can change over time. Malay leaves the verb uninflected and uses time or aspect expressions around mampu:
Dahulu dia mampu berlari sejauh sepuluh kilometer, tetapi sekarang dia cepat penat.
She used to be able to run ten kilometers, but now she tires quickly.
Selepas beberapa minggu menjalani fisioterapi, dia akan mampu berjalan semula.
After several weeks of physiotherapy, she will be able to walk again.
Dahulu locates former capacity; akan projects future capacity. Mampu itself does not conjugate for past or future.
Mental, emotional, and technical capacity
Capacity need not be muscular. A person may have the understanding, concentration, courage, or emotional resilience required to cope with something.
Pelajar itu mampu menerangkan konsep yang rumit dengan bahasa yang mudah.
That student is capable of explaining a complex concept in simple language.
Saya belum mampu membincangkan pengalaman itu secara terbuka.
I am not yet able to discuss that experience openly.
Belum mampu means that the capacity has not been reached yet and often leaves room for change. Tidak mampu simply denies present capacity. In sensitive contexts, this difference can matter: belum mampu may sound hopeful, while tidak mampu can sound more categorical.
Technical capacity also fits the same construction:
Juruteknik kami mampu memulihkan data daripada pemacu yang rosak itu.
Our technician is capable of recovering data from that damaged drive.
The sentence attributes expertise or resources. To report a particular successful recovery, use berjaya memulihkan or contextually dapat memulihkan, because capacity and completed achievement are not identical.
Financial capacity
One of the most frequent uses of mampu concerns affordability. The subject has or lacks sufficient financial resources for a payment, purchase, or commitment.
Dengan pendapatan sekarang, mereka mampu membayar sewa rumah itu tanpa berhutang.
With their current income, they can afford to pay the rent on that house without going into debt.
Ramai keluarga tidak mampu membeli rumah berhampiran pusat bandar.
Many families cannot afford to buy a home near the city centre.
Adakah syarikat itu mampu menanggung kos penyelenggaraan selama lima tahun?
Can that company afford to bear the maintenance costs for five years?
The statement mampu membayar concerns affordability even before money changes hands. Dapat membayar semalam may report that payment was successfully made; boleh membayar dengan kad may state an accepted method. English can pay leaves those readings more dependent on context.
Golongan kurang mampu is an established polite description for people with limited economic means (formal/public discourse). Literally, kurang mampu means “less able,” but in this noun phrase the financial interpretation is conventional.
Dana itu menyediakan bantuan persekolahan kepada keluarga kurang mampu.
The fund provides school assistance to lower-income families. (formal/public discourse)
Institutional and collective capacity
Institutions have no muscles or personal wishes, but they possess staff, equipment, legal authority, budgets, and systems. Mampu can evaluate whether those combined resources meet a demand.
Hospital daerah itu mampu merawat sehingga dua ratus orang pesakit luar sehari.
The district hospital has the capacity to treat up to two hundred outpatients a day. (formal)
Tanpa peruntukan tambahan, majlis tempatan tidak mampu menyelenggarakan semua kemudahan awam tersebut.
Without additional funding, the local council lacks the capacity to maintain all those public facilities. (formal)
Sistem sedia ada mampu mengendalikan jumlah permohonan yang diterima pada masa ini.
The existing system can handle the number of applications currently received. (technical/formal)
These statements should ideally be supported by evidence: bed numbers, staffing, throughput, or budget. Mampu makes a capacity claim; it does not merely predict that an institution will act.
Adjective-like predication
Mampu can serve as the predicate of a clause and can combine with degree or aspect words. The action may be expressed after it or recovered from context.
Kosnya tinggi, tetapi kami masih mampu.
The cost is high, but we can still afford it.
Pasukan kecil itu lebih mampu menyesuaikan diri dengan perubahan mendadak.
That small team is better able to adapt to sudden changes.
In the first sentence, the previous mention of cost supplies the understood financial demand. In the second, lebih grades capacity. This adjective-like behavior helps explain kurang mampu, masih mampu, belum mampu, and tidak mampu.
Do not insert a Malay copula simply because English uses be able. Dia adalah mampu membayar is not the ordinary construction; use Dia mampu membayar.
Mampu and optional untuk
The direct pattern mampu + verb is concise and natural across registers:
Pasukan itu mampu menyelesaikan tugas tersebut sebelum tarikh akhir.
The team is capable of completing the task before the deadline.
Mampu untuk + verb is also attested, especially when the complement is long or the writer gives it extra separation. Untuk is optional here, not an infinitive ending.
Dengan latihan yang mencukupi, kakitangan baharu itu mampu untuk mengendalikan pertanyaan pelanggan yang lebih rumit.
With sufficient training, the new staff member is capable of handling more complex customer enquiries. (careful/formal)
Many editors would still prefer the leaner mampu mengendalikan. Neither version changes the following verb for person or tense. Avoid repeating untuk mechanically after every modal word; its acceptability depends on the construction.
Mampu versus boleh, dapat, and sempat
| Form | Main question | Example meaning |
|---|---|---|
| mampu | Does the subject have enough capacity or resources? | can afford/can cope |
| boleh | Is it permitted, acceptable, or situationally possible? | may enter / can be done |
| dapat | Can the result be obtained or achieved? | managed/can obtain |
| sempat | Is there enough opportunity or time? | had time/chance to do it |
Anda boleh masuk sekarang; pegawai bertugas sudah memberikan kebenaran.
You may enter now; the duty officer has given permission.
Walaupun pintunya tersekat, anggota bomba berjaya membukanya.
Although the door was jammed, the firefighters managed to open it.
Saya tidak sempat bersarapan sebelum menaiki bas.
I did not have time to eat breakfast before boarding the bus.
None of these statements primarily evaluates underlying capacity. A strong person may be mampu to open a door but fail in one attempt; a visitor may be physically mampu to enter but not boleh enter without permission.
See boleh for permission and boleh for ability and situational possibility for the most important contrast.
Common Mistakes
1. Using mampu for permission
❌ Pelawat mampu masuk ke wad sekarang.
Wrong for the intended permission—the sentence merely claims that visitors are capable of entering.
✅ Pelawat boleh masuk ke wad dari pukul dua hingga pukul empat petang.
Visitors may enter the ward from two until four in the afternoon.
2. Using mampu to report one completed success
❌ Anggota bomba mampu membuka pintu yang tersekat itu semalam.
Misleading for the intended completed achievement—mampu states capacity, not that this attempt succeeded.
✅ Anggota bomba berjaya membuka pintu yang tersekat itu semalam.
The firefighters managed to open the jammed door yesterday.
3. Adding a copula before mampu
❌ Keluarga itu adalah mampu membayar yuran tersebut.
Incorrect ordinary predication—mampu functions directly as the predicate.
✅ Keluarga itu mampu membayar yuran tersebut secara ansuran.
That family can afford to pay the fee in instalments.
4. Treating untuk as compulsory
⚠️ Selepas kemalangan itu, dia masih tidak mampu untuk berdiri sendiri.
Grammatical but heavier than necessary—untuk is optional, not required after mampu.
✅ Selepas kemalangan itu, dia masih tidak mampu berdiri sendiri.
After the accident, she was still unable to stand unaided.
5. Confusing lack of time with lack of capacity
❌ Saya tidak mampu membalas e-mel itu pagi tadi kerana mesyuarat berterusan.
Wrong for the intended lack of opportunity—the issue was time, not underlying ability.
✅ Saya tidak sempat membalas e-mel itu pagi tadi kerana mesyuarat berterusan.
I did not have time to reply to that email this morning because the meeting ran on.
Key Takeaways
Mampu evaluates underlying physical, mental, financial, technical, or institutional capacity. It combines directly with an action, while mampu untuk + action is an optional heavier variant. Negate it with tidak mampu, use belum mampu when the capacity has not yet developed, and recognize adjective-like masih/lebih/kurang mampu. Choose boleh for permission, sempat for available time, and berjaya/dapat when a particular achievement—not merely capacity—is central.
