Pelanggan memeriksa nombor akaun dan caj semasa.

The sentence follows the very common Malay pattern:

Subject + Verb + Object

• Pelanggan = subject
• memeriksa = verb
• nombor akaun dan caj semasa = object

So Malay is often similar to English in simple sentences:

• The customer
  • checks
    • the account number and current charges

Periksa is the root word, meaning something like inspect / check / examine.

Memeriksa is the active verb form built from that root. In Malay, this kind of verb often takes the meN- prefix. So:

• periksa = root
• memeriksa = to check / checks / is checking

In a normal sentence with a subject doing the action, memeriksa sounds more natural and complete than bare periksa.

Very roughly:

• Pelanggan memeriksa... = The customer checks...
• Periksa nombor akaun! = Check the account number!
  Here periksa can appear as a command.

Not by itself. Malay verbs usually do not change for tense the way English verbs do.

So memeriksa can mean:

• checks
• is checking
• sometimes even checked / will check, if the context makes that clear

Time is usually shown by context or time words, such as:

• semalam = yesterday
• sekarang = now
• esok = tomorrow
• sedang = currently/in the middle of
• akan = will

So this sentence does not grammatically force a tense in the same way English does.

By itself, pelanggan can be singular or plural, depending on context.

It can mean:

• customer
• customers

If Malay wants to make plurality very explicit, it can use:

• para pelanggan = customers
• pelanggan-pelanggan = customers

But in many cases, Malay leaves number unstated unless it matters. So this sentence could mean the customer checks... or customers check..., depending on context.

In Malay, noun combinations often work in the order:

main noun + describing noun

So:

• nombor akaun = literally number account
• natural English equivalent: account number

This is very common in Malay. The second noun helps specify the first noun.

Compare:

• kad kredit = credit card
• bilik hotel = hotel room
• nombor telefon = telephone number / phone number

So even though English says account number, Malay naturally says nombor akaun.

Here, semasa means current.

So:

• caj semasa = current charges

In Malay, adjectives usually come after the noun they describe, so:

• caj = charge(s)
• semasa = current
• caj semasa = current charge(s)

Also, semasa can have other meanings in other contexts, such as during or while, but in this sentence it is clearly acting as an adjective describing caj.

Normally, it describes only caj.

So the structure is understood as:

• nombor akaun
  and
• caj semasa

In other words:

• account number
• current charges

not:

• current account number and charges

This is because adjectives in Malay usually follow the noun they describe, and semasa comes right after caj.

Malay usually does not use articles like the or a/an the way English does.

So:

• Pelanggan could mean a customer, the customer, or even customers, depending on context.
• nombor akaun could mean an account number or the account number
• caj semasa could mean current charges or the current charges

Malay relies much more on context than English does for this kind of information.

Yes, both are loanwords used in Malay.

• akaun comes from account
• caj comes from charge

Their spelling has been adapted to Malay spelling conventions:

• account → akaun
• charge → caj

This is very common in modern Malay, especially in business, technology, and administration.

A simple approximate guide for an English speaker:

• pelanggan ≈ puh-LANG-gan
• memeriksa ≈ muh-muh-RIK-sah
• nombor ≈ NOM-bor
• akaun ≈ ah-KA-un
• caj ≈ chaj
• semasa ≈ suh-MAH-suh

A few useful pronunciation notes:

• Malay spelling is generally quite regular.
• c in Malay is pronounced like English ch.
• j is like English j in jam.
• Final vowels are usually pronounced clearly.

It sounds neutral and fairly standard. It would fit well in:

• customer service contexts
• banking or billing interfaces
• business writing
• textbook examples

Nothing in it is especially slangy or highly literary. It is the kind of straightforward Malay you might see in practical, everyday professional use.

Yes, very naturally.

Words like:

• pelanggan = customer
• nombor akaun = account number
• caj semasa = current charges

strongly suggest a context such as:

• banking
• utilities
• telecom billing
• online account management
• customer service systems

So this feels like the kind of sentence you might see in an app, website, or help document.
