Juruelektrik memeriksa fius ini.

• juruelektrik = electrician
• memeriksa = checks / examines / inspects
• fius = fuse
• ini = this

So the structure is basically:

Juruelektrik + memeriksa + fius ini
The electrician + checks/is checking + this fuse

In Malay, demonstratives like ini (this) and itu (that) usually come after the noun.

So:

• fius ini = this fuse
• rumah ini = this house
• kereta itu = that car

This is normal Malay word order. It is different from English, where this comes before the noun.

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

So:

• juruelektrik can mean an electrician, the electrician, or just electrician
• fius can mean a fuse, the fuse, or just fuse

The exact meaning depends on context. In this sentence, the presence of ini makes fius ini clearly mean this fuse.

The base word is periksa = inspect / examine / check.

Malay often adds the prefix meN- to form an active verb. Here, periksa becomes memeriksa.

So:

• periksa = the root word
• memeriksa = to inspect / is inspecting / inspects

This is a very common pattern in Malay. The meN- prefix often marks an active verb used with a subject doing the action.

This happens because Malay prefixes change shape depending on the first sound of the root word.

With periksa, the prefix becomes mem-, giving memeriksa.

This kind of sound change is very common in Malay verb formation. A learner does not need to master every pattern immediately, but it is useful to know that:

• the dictionary/root form may look different from the verb form
• meN- has several surface forms such as mem-, men-, meng-, and meny-

Yes, juruelektrik is written as one word.

It is made from:

• juru- = a person skilled in or responsible for something
• elektrik = electric / electricity

So juruelektrik literally means something like electric specialist/worker, which corresponds to electrician.

Malay often forms occupation words this way, and many of them are written as single words.

By itself, memeriksa does not mark tense the way English verbs do.

So Juruelektrik memeriksa fius ini can mean:

• The electrician checks this fuse
• The electrician is checking this fuse

depending on context.

Malay usually shows time with:

• context
• time words such as semalam (yesterday), sekarang (now), esok (tomorrow)
• aspect markers such as sedang, sudah, akan

Examples:

• Juruelektrik sedang memeriksa fius ini = The electrician is checking this fuse.
• Juruelektrik sudah memeriksa fius ini = The electrician has checked / checked this fuse.

Malay nouns usually do not change form for singular vs. plural.

So fius can mean:

• fuse
• fuses

In this sentence, fius ini is most naturally understood as this fuse, so singular makes the most sense.

If you wanted to make plurality very clear, Malay might use:

• context
• a number
• reduplication, such as fius-fius

For example:

• fius-fius ini = these fuses

But in everyday Malay, number is often left unmarked unless it needs to be clarified.

Yes. The basic word order here is:

Subject + Verb + Object

• Juruelektrik = subject
• memeriksa = verb
• fius ini = object

This is a very common and natural sentence pattern in Malay, similar to English: The electrician checks this fuse.

Yes, it is natural.

However, depending on context, a speaker might add extra words:

• Juruelektrik sedang memeriksa fius ini = The electrician is checking this fuse right now.
• Seorang juruelektrik memeriksa fius ini = An electrician checks/is checking this fuse.

The original sentence is perfectly fine as a simple neutral statement.

Malay can sometimes omit the subject if it is obvious from context, but in a standalone sentence, keeping juruelektrik makes it clearer.

So:

• Juruelektrik memeriksa fius ini = clear, complete sentence
• Memeriksa fius ini = may sound incomplete on its own unless the context already makes the subject obvious

English learners should usually include the subject unless they know the context allows it.

To negate a verb in Malay, you usually use tidak before the verb.

So:

• Juruelektrik tidak memeriksa fius ini = The electrician does not/is not checking this fuse.

This is the normal way to negate an action.

A simple way is to use intonation in speech or a question word in context.

For a yes-no question, you can say:

• Juruelektrik memeriksa fius ini? = Is the electrician checking this fuse?

In more formal or careful Malay, you might also use question particles or fuller phrasing, but for a beginner, understanding that plain statement order can work as a question is very useful.
