Doktor itu menjelaskan penyakit.

Malay basic word order is usually Subject + Verb + Object, just like English.

• Doktor itu = the doctor
• menjelaskan = explains / explained / is explaining
• penyakit = the disease / illness

So the sentence follows the normal pattern:

subject → verb → object

That makes Doktor itu menjelaskan penyakit a very straightforward Malay sentence.

In this sentence, itu helps mark doktor as a specific doctor.

So doktor itu usually means:

• that doctor
• or, depending on context, the doctor

Malay often uses itu after a noun to point to something already known, specific, or identifiable.

A useful thing to notice is that itu comes after the noun:

• doktor itu = that/the doctor
• not itu doktor in this kind of noun phrase

Because in Malay, demonstratives like ini (this) and itu (that) normally come after the noun.

Examples:

• doktor ini = this doctor
• doktor itu = that doctor
• rumah itu = that house
• buku ini = this book

This is different from English, where we say that doctor.

Menjelaskan is a verb formed from a root plus affixes.

The root is jelas, which relates to the idea of being clear.

From that root, Malay forms the verb menjelaskan, which means something like:

• to explain
• to make clear
• to clarify

So the verb is longer because Malay often builds words by adding prefixes and suffixes to a root.

A learner does not need to fully analyze every part at first, but it helps to know that:

• jelas = clear
• menjelaskan = explain / make clear

Because jelas by itself is usually not the right form for explain.

• jelas is mainly an adjective or stative idea: clear
• menjelaskan is the active verb: to explain

Compare the difference in English:

• clear = adjective
• to clarify / explain = verb

So if you want to say that the doctor explains something, menjelaskan is the natural form.

Malay does not use articles like a, an, and the the way English does.

So penyakit can mean:

• disease
• a disease
• the disease
• illness
• the illness

The exact meaning depends on context.

That is very normal in Malay. Learners often expect every noun to need a word like the, but Malay usually leaves that unstated unless it needs to be made specific in some other way.

Yes. Penyakit can cover meanings like:

• disease
• illness
• sickness

The best English translation depends on context.

So even if one translation is given to the learner, it is useful to know that Malay words often do not match one single English word perfectly.

No, not by itself. Malay verbs usually do not change form to show tense the way English verbs do.

So menjelaskan can mean:

• explains
• is explaining
• explained
• sometimes will explain

The time is usually understood from context or from time words such as:

• semalam = yesterday
• sekarang = now
• esok = tomorrow

So Doktor itu menjelaskan penyakit does not automatically tell you whether it is present or past without more context.

Yes, in a general sense, menjelaskan penyakit means explains/explained the disease or explains/explained about the disease, depending on context.

But if you want to clearly include the person receiving the explanation, Malay often adds that information, for example with another phrase after the object.

This sentence as given only tells us:

• who did the explaining: doktor itu
• what was explained: penyakit

It does not state who the explanation was given to.

No, doktor is a borrowed word, ultimately from the same source as English doctor. Malay has many borrowed words, including from Sanskrit, Arabic, Portuguese, Dutch, and English.

For a learner, this is helpful because some vocabulary may look familiar. However, pronunciation and usage may still be different.

A simple approximate pronunciation for an English speaker is:

dok-tor ee-too men-juh-LAS-kan pen-yah-keet

A few helpful notes:

• doktor: both syllables are pronounced clearly
• itu: sounds like ee-too
• menjelaskan: the j sounds like English j in jam
• penyakit: the ny sounds like ny in canyon

Malay pronunciation is generally more regular than English spelling, so once you learn the sound system, reading becomes easier.
