Cakupan dijelaskan dalam polis.

Because di- here is a prefix, not a separate preposition.

• dijelaskan = di-
  • jelas
    • -kan
• This makes a passive verb: to be explained

Compare:

• dijelaskan = is explained → one word
• di polis = in/on the policy → di as a preposition, written separately

This is a very common point for learners:

• di-
  • verb = one word
• di
  • place = two words

So in this sentence:

• dijelaskan is correct
• dalam polis is separate because dalam is a preposition

Yes. Cakupan dijelaskan dalam polis is a passive sentence.

It literally works like:

• cakupan = coverage
• dijelaskan = is explained
• dalam polis = in the policy

So the structure is roughly:

• Subject/topic + passive verb + location

Indonesian uses the prefix di- to form many passive verbs.
That is why dijelaskan means is explained.

Indonesian often does not use a separate verb like is / am / are in the way English does.

In this sentence, the passive meaning is already built into dijelaskan:

• jelaskan relates to explain
• dijelaskan means is explained or are explained, depending on context

So English needs is explained, but Indonesian can express that with just one verb form: dijelaskan.

Cakupan generally means coverage, scope, or range, depending on context.

In this sentence, because of polis, it most likely means coverage in the insurance sense.

Examples of possible meanings in different contexts:

• cakupan asuransi = insurance coverage
• cakupan topik = scope of topics
• cakupan wilayah = area coverage

So the exact meaning depends on context, but with polis, coverage is the natural reading.

No. Here polis means policy, especially an insurance policy.

So:

• polis = policy
• polisi = police

These two words are easy to confuse for English speakers because they look similar.

In this sentence:

• dalam polis = in the policy
• more specifically, in the insurance policy

Dalam means in / inside / within, and it often sounds more natural when talking about information contained in a document.

So:

• dalam polis = in the policy
• di polis is generally less natural here

For documents, texts, and written contents, dalam is often preferred when meaning within the contents of something.

So Cakupan dijelaskan dalam polis sounds natural as:

• The coverage is explained in the policy

Yes, you could. Di dalam polis is possible, but it may sound a little more explicit or slightly heavier than dalam polis.

Comparison:

• dalam polis = natural and concise
• di dalam polis = also understandable, with a stronger sense of inside/within

In many contexts involving written documents, dalam polis is the smoother choice.

The core root is jelas, which means clear.

From that root, Indonesian forms related words:

• jelas = clear
• menjelaskan = to explain
• dijelaskan = to be explained
• penjelasan = explanation

So dijelaskan is related to the idea of making something clear.

A useful way to see it:

• menjelaskan = actively explain
• dijelaskan = be explained

Yes. If you want to mention the agent, Indonesian often uses oleh = by.

Example:

• Cakupan dijelaskan oleh perusahaan dalam polis.
• The coverage is explained by the company in the policy.

But in many Indonesian sentences, especially formal or informational ones, the agent is simply omitted if it is obvious or unimportant.

That is why Cakupan dijelaskan dalam polis sounds natural on its own.

Yes, it sounds fairly formal and is very natural in insurance, legal, or business contexts.

Why it feels formal:

• cakupan is a formal noun
• dijelaskan is a standard passive form
• polis belongs to insurance/legal vocabulary

In everyday casual speech, people might use a more conversational sentence, depending on context. But for official documents, websites, contracts, or customer information, this sentence is perfectly normal.

Yes, somewhat. Indonesian word order is flexible, especially for emphasis.

For example:

• Cakupan dijelaskan dalam polis. = neutral, standard
• Dalam polis, cakupan dijelaskan. = emphasizes in the policy

Both are grammatical, but the original version is the more straightforward default.

So if you want to say where the explanation is found, fronting dalam polis can add emphasis.
