Keadaan akan kekal demikian sehingga esok.

Akan marks future time. In this sentence, it tells you that the situation will remain that way.

So:

• keadaan = the situation/state/condition
• akan = will
• kekal = remain
• demikian = like that / in that way / thus
• sehingga esok = until tomorrow

Malay does not always have to mark the future, especially if the time is already clear from context, but akan is a very common and clear way to do it.

Yes. Here kekal functions as a verb, meaning to remain or to stay unchanged.

In English, remain is a verb, and kekal works similarly here:

• Keadaan akan kekal demikian = The situation will remain that way.

Depending on context, kekal can also feel adjective-like in some expressions, but in this sentence it is best understood as the main predicate meaning remain.

Keadaan is a noun meaning state, condition, or situation.

It is a fairly general and common word. In this sentence, it refers to the overall circumstances or condition of something.

Some rough English equivalents depending on context:

• state
• condition
• situation

So keadaan is the thing that will remain unchanged.

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

So keadaan can mean:

• a situation
• the situation
• the condition
• a condition

Which one is intended depends on context.

In this sentence, English would often naturally translate it as the situation, but Malay does not need a separate word for the.

Demikian means something like thus, like that, or in that manner. It is a bit more formal or written in tone than begini or begitu.

A rough comparison:

• begini = like this
• begitu = like that
• demikian = thus / in that way / like that (more formal)

So kekal demikian means remain that way or remain as such.

If you replaced it with begitu, the sentence would sound less formal and more conversational:

• Keadaan akan kekal begitu sehingga esok.

That would still be understandable.

Yes, sampai could often be used in similar contexts, but sehingga is usually a bit more formal and often appears in writing.

Comparison:

• sehingga esok = until tomorrow
• sampai esok = until tomorrow

In everyday speech, sampai is very common. In more formal writing, sehingga may sound more natural.

So this sentence has a somewhat formal or neutral-written style partly because of demikian and sehingga.

Because with time expressions like esok (tomorrow), Malay normally does not use ke here.

So you say:

• sehingga esok = until tomorrow

not:

• sehingga ke esok in normal standard usage for this meaning

The preposition ke is often used for movement toward a place or in some other constructions, but it is not needed before esok here.

Yes, it often can be omitted if the time reference is already obvious from context.

For example:

• Keadaan kekal demikian sehingga esok.

This can still be understood, especially if the surrounding context already makes the future meaning clear. However, adding akan makes the future meaning more explicit:

• Keadaan akan kekal demikian sehingga esok.

So akan is not always grammatically required, but it is useful and natural.

The normal order here is:

• Keadaan
  • akan
    • kekal
      • demikian
        • sehingga esok

This is a very natural order in Malay.

You may sometimes see variations for emphasis or style, but for a learner, this order is the best one to follow.

For example, moving demikian around may sound unnatural unless you are already comfortable with more advanced Malay style. So the safest pattern is:

subject/topic + time/modal marker + verb + complement + time phrase

Usually, yes.

Demikian often points back to a previously described state or situation. It means something like:

• that way
• in such a manner
• as described

So this sentence often makes the most sense when the listener already knows what state is being talked about.

Without earlier context, demikian can sound a little abstract, because it is referring to some already-known situation.

It sounds fairly formal or neutral written rather than casual everyday speech.

That is mainly because of:

• demikian instead of begitu
• sehingga instead of sampai

A more conversational version might be:

• Keadaan akan kekal begitu sampai esok.

That said, the original sentence is perfectly natural, especially in formal statements, reports, announcements, or written explanations.

Yes, depending on what exactly you mean.

Possible alternatives include:

• situasi = situation
• kondisi = condition
• keadaan semasa = current situation

But keadaan is a very common and flexible choice. It sounds natural and broadly applicable.

For example:

• Situasi akan kekal demikian sehingga esok.
• Kondisi akan kekal demikian sehingga esok.

These are possible, but keadaan is often the safest general word.

Yes, especially in a formal or written context.

It sounds like something you might read or hear in:

• an announcement
• a weather or traffic update
• a report
• an official statement

In casual conversation, a speaker might choose simpler words, such as:

• Keadaan akan kekal begitu sampai esok.

So the original sentence is natural, but it leans toward a more formal register.
