Kes itu mengenai kemalangan.

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

So:

• kes itu = that case / the case
• kemalangan itu = that accident / the accident

This is different from English, where this/that/the normally comes before the noun.

It can function as either, depending on context.

In Kes itu mengenai kemalangan, kes itu could be understood as:

• that case
• the case

Malay does not have a separate word exactly like English the, so itu is often used when the noun is definite or already known from context.

No. Malay often does not need a verb like is/are in the same way English does.

So:

• Kes itu mengenai kemalangan. = The case is about an accident.

The sentence is complete without adding is.

You may sometimes see adalah in formal writing, but it is not always necessary, and in many everyday sentences Malay simply leaves the copula out.

Mengenai means about, regarding, or concerning.

In this sentence:

• Kes itu mengenai kemalangan = The case concerns an accident = The case is about an accident

It is common in formal or neutral contexts, such as reports, news, school writing, or official language.

Yes, often you can.

• Kes itu mengenai kemalangan
• Kes itu tentang kemalangan

Both can mean The case is about an accident.

However, mengenai often sounds a bit more formal or official than tentang. In legal, police, or report-like contexts, mengenai may sound more natural.

Kemalangan means accident.

It comes from the root malang, which is related to bad luck or misfortune. The pattern ke-...-an often forms nouns in Malay.

So:

• malang = unfortunate / unlucky
• kemalangan = accident / misfortune

In modern usage, kemalangan is a very common word for accident, especially things like traffic accidents.

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

So kemalangan could mean:

• an accident
• the accident

The exact meaning depends on context.

That means Kes itu mengenai kemalangan could be translated as either:

• The case is about an accident
• The case is about the accident

Both are possible depending on the situation.

Yes. Kes is a loanword from English case.

In Malay, kes is commonly used in contexts like:

• legal cases
• police cases
• medical cases
• incidents being discussed or investigated

Even though it came from English, it is now a normal Malay word.

The structure is:

• Kes itu = the/that case
• mengenai kemalangan = about an accident / concerning the accident

So the pattern is roughly:

• Noun phrase + mengenai + noun

Literally, you could think of it as:

• The case concerning an accident

Natural English adds is:

• The case is about an accident

You can find sentences like that, especially in formal writing, but it often sounds heavier than necessary.

Most natural versions would be:

• Kes itu mengenai kemalangan.
• Kes itu tentang kemalangan.

Malay often prefers the shorter version without adalah unless there is a specific stylistic or formal reason to include it.

For learners, it is easiest to treat mengenai here as meaning about / concerning.

In real grammar discussions, it can behave in ways that are somewhat verb-like historically, but in this sentence its function is basically to link kes itu with the topic kemalangan.

So for practical purposes:

• mengenai = about / concerning

That is the most useful way to understand it.

It sounds natural in formal or semi-formal contexts, such as:

• police reports
• legal discussion
• news reports
• written summaries
• school essays

For example, someone might say it when introducing a topic:

• Kes itu mengenai kemalangan jalan raya. = The case concerns a road accident.

So the sentence has a slightly official or factual tone rather than a casual conversational one.
