Hindi pa rin kumpleto ang aplikasyon.

It means something like still not or not yet ... still.

In this sentence:

• hindi = not
• pa = still / yet
• rin = still / anyway / also, depending on context

Together, hindi pa rin kumpleto means is still not complete.

So the sentence expresses that the application remains incomplete up to now.

Filipino often puts the predicate first and the topic marked by ang after it.

Here:

• Hindi pa rin kumpleto = the predicate
• ang aplikasyon = the topic / the thing being talked about

So the structure is very normal in Filipino:

• Hindi pa rin kumpleto ang aplikasyon.

A more English-like order is also possible:

• Ang aplikasyon ay hindi pa rin kumpleto.

That version is grammatical too, but it sounds a bit more formal or more deliberately structured.

Ang marks the noun phrase that is the topic or focus of the sentence.

So in:

• ang aplikasyon

the speaker is identifying the application as the thing being described.

In this sentence, the application is the thing that is still not complete.

For English speakers, it can help to think of ang as a marker that says, this is the main noun phrase I’m talking about. It is not exactly the same as the, even though English translations often use the.

Yes. Kumpleto is an adjective meaning complete.

In this sentence, it works as a predicate adjective, meaning it describes the topic:

• Hindi pa rin kumpleto ang aplikasyon.
• The application is still not complete.

If you wanted to use kumpleto directly before a noun, you would normally need a linker:

• kumpletong aplikasyon = complete application

But in your sentence, kumpleto is not directly modifying aplikasyon inside one noun phrase. It is the predicate of the sentence.

Because kumpleto is not being used attributively here.

Compare these:

• kumpletong aplikasyon = complete application

  • here kumpleto directly modifies aplikasyon
  • so a linker is needed

• Kumpleto ang aplikasyon = The application is complete

  • here kumpleto is the predicate
  • ang aplikasyon is the topic
  • no linker is used

So your sentence follows the second pattern.

Yes, you can say:

• Hindi pa kumpleto ang aplikasyon.

That means The application is not complete yet.

Adding rin gives a stronger sense of still or even now:

• Hindi pa rin kumpleto ang aplikasyon.
• The application is still not complete.

So:

• hindi pa = not yet
• hindi pa rin = still not yet / still not

The version with rin emphasizes that the incomplete state continues.

This is due to a common sound-based rule in Filipino.

Usually:

• din is used after most consonants
• rin is used after words ending in a vowel, w, or y

Since pa ends in a vowel, rin is the expected form:

• pa rin

So Hindi pa rin kumpleto... is the standard form.

In casual speech, some speakers may use din more freely, but for learners, pa rin is the best choice here.

Because hindi negates adjectives, verbs, and whole statements, while wala usually means there is none / there is no / absent.

Here, kumpleto is an adjective, so you negate it with hindi:

• Hindi kumpleto = not complete

Using wala would not fit this structure.

Compare:

• Hindi kumpleto ang aplikasyon. = The application is not complete.
• Walang aplikasyon. = There is no application.

Those mean different things.

Yes. That is also correct.

Compare:

• Hindi pa rin kumpleto ang aplikasyon.
• Ang aplikasyon ay hindi pa rin kumpleto.

Both mean the same thing.

The difference is mostly in style and emphasis:

• Predicate-first (Hindi pa rin kumpleto...) is very common and natural in everyday Filipino.
• Topic-first with ay (Ang aplikasyon ay...) can sound more formal, more written, or more emphatic.

No, it is a borrowed word, ultimately from Spanish and English influence. It is fully normal in modern Filipino.

For many contexts, aplikasyon is the standard and natural word for application, especially for forms, school applications, job applications, and official processes.

So this sentence sounds natural and standard.

Yes, many speakers write and say kompleto as well. Both spellings are seen.

However, kumpleto is a standard Filipino-style spelling and is very common in educational or formal Filipino writing.

So:

• Hindi pa rin kumpleto ang aplikasyon.
• Hindi pa rin kumpleto ang application.
• Hindi pa rin kompleto ang aplikasyon.

You may encounter variation, but kumpleto is perfectly good and standard.

This is a very important contrast.

• hindi pa kumpleto = not complete yet
• hindi na kumpleto = no longer complete

So:

• Hindi pa rin kumpleto ang aplikasyon.
  = The application is still not complete.

But:

• Hindi na kumpleto ang aplikasyon.
  = The application is no longer complete.

That second one would imply it used to be complete, or that something is now missing. So the meaning changes a lot.

Yes, absolutely. That is one of the most natural uses.

Aplikasyon can refer not just to a physical form, but to the whole application submission or process. So the sentence can mean that some part is missing, such as:

• documents
• signatures
• information
• requirements
• attachments

So Hindi pa rin kumpleto ang aplikasyon can naturally mean that the application package or application process is still incomplete.
