Sariawan ini belum sembuh.

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

So:

• sariawan ini = this canker sore
• rumah ini = this house
• buku itu = that book

That word order is normal in Indonesian.

Belum means not yet. It shows that something has not happened up to now, but it may happen later.

So belum sembuh means has not healed yet or is not better yet.

This is different from a plain negative like tidak, which usually just means not.

Because the idea is not yet, not just not.

• belum sembuh = not healed yet
• tidak sembuh = not healed / did not heal

In many situations, tidak sembuh can sound stronger or more final, while belum sembuh suggests there is still a possibility of recovery.

Sembuh means healed, recovered, or well again. It is commonly used for illnesses, injuries, and physical conditions.

Examples:

• Saya sudah sembuh. = I’ve recovered / I’m better now.
• Lukanya belum sembuh. = The wound hasn’t healed yet.

In this sentence, sembuh refers to the sore healing.

It can behave a bit like both, which is common in Indonesian.

In Sariawan ini belum sembuh, you can think of sembuh as meaning:

• healed / better as a state, or
• to heal / recover as a process

Indonesian often does not separate these categories as strictly as English does.

Indonesian often leaves out a verb like to be. It also does not need auxiliary verbs like has the way English does.

So instead of saying something like This canker sore has not healed yet, Indonesian simply says:

• Sariawan ini belum sembuh.

Time and aspect are usually shown through words like sudah (already) and belum (not yet), or through context.

It can match either in English, depending on context.

• isn’t healed yet
• hasn’t healed yet

Both capture the meaning of belum sembuh well. Indonesian does not force the same tense distinction that English does here.

Not by itself. Sariawan ini literally means this canker sore.

However, in real conversation, a speaker might be pointing to or referring to their own sore, so English may naturally translate it as my canker sore if the context is obvious.

If you want to say my canker sore explicitly, you would say:

• sariawan saya

Yes, it sounds natural. It is a simple, common way to say that a mouth ulcer has not gotten better yet.

Other natural variations include:

• Sariawan saya belum sembuh. = My canker sore hasn’t healed yet.
• Sariawannya belum sembuh. = The canker sore hasn’t healed yet / his-her canker sore hasn’t healed yet, depending on context.

You would usually say:

• Sariawan ini sudah sembuh.

Here, sudah means already.

So the contrast is:

• belum sembuh = not healed yet
• sudah sembuh = already healed

A simple pronunciation guide is:

• sariawan ≈ sa-ree-A-wan
• ini ≈ ee-nee
• belum ≈ buh-LUM
• sembuh ≈ sem-booh

A rough full pronunciation:

sa-ree-A-wan ee-nee buh-LUM sem-booh

The r in Indonesian is usually trilled or tapped, and uh in sembuh is not the English uh sound in cup; it is closer to an Indonesian u-like sound at the end.

The pattern is:

• noun + ini + belum + predicate

So:

• sariawan = noun
• ini = this
• belum = not yet
• sembuh = healed / recovered

A very literal breakdown is:

• canker sore this not-yet healed

Natural English:

• This canker sore hasn’t healed yet.
