Pagkatapos ng kumpirmasyon, subaybayan ang paghahatid ng rehistradong koreo.

Literally, it is after the confirmation.

• pagkatapos = after
• ng kumpirmasyon = of confirmation / the confirmation

As a whole, it works like an introductory time phrase: After confirmation, ...

After pagkatapos, Filipino normally uses ng to introduce the event or thing that comes first in time.

So you get patterns like:

• pagkatapos ng klase = after class
• pagkatapos ng trabaho = after work
• pagkatapos ng kumpirmasyon = after confirmation

Here, ng is not really best understood as a literal English of. It is just the normal marker used in this structure.

Yes. In this sentence, subaybayan is being used as an instruction or command: track / monitor.

Filipino often leaves out the word for you in commands when it is obvious. So:

• Subaybayan ang paghahatid... = Track the delivery...
• Subaybayan mo ang paghahatid... = You track the delivery...

Both are possible, but the shorter version is very common in instructions.

It comes from the root subaybay, which has the idea of following, tracking, or monitoring.

The form subaybayan is a verb built from that root and is used when the thing being tracked is the focus of the sentence. In practical terms, learners can remember it here as:

• subaybay = tracking/following
• subaybayan = track something / monitor something

Paghahatid means delivery or the act/process of delivering.

It comes from the root hatid, which is related to bringing or delivering. The pag- form turns it into a verbal noun, similar to English delivery from deliver.

So:

• hatid = deliver/bring
• paghahatid = delivery

The sentence says subaybayan ang paghahatid, which means track the delivery process. That is different from telling someone to deliver something.

This is about how the parts of the sentence are connected.

• ang paghahatid = the delivery
  This is the main thing being tracked.
• ng rehistradong koreo = of registered mail
  This tells you what kind of delivery it is.

So the structure is basically:

Track + the delivery + of registered mail

In other words, ang marks the main noun phrase tied to subaybayan, while ng links rehistradong koreo to paghahatid.

Rehistradong koreo means registered mail.

• rehistrado = registered
• koreo = mail / post

The -ng on rehistradong is a linker. Filipino uses a linker to connect a modifier to the noun it describes.

So:

• rehistrado
  • -ng
    • koreo
• rehistradong koreo

This is a very common pattern in Filipino grammar.

Yes. Kumpirmasyon is a normal and understandable Filipino word, especially in formal or administrative language.

It is a loanword, and that is very common in Filipino. In official instructions, forms, websites, and service messages, words like this are very natural.

A more native-looking alternative such as pagkumpirma may also exist in some contexts, but kumpirmasyon sounds perfectly normal here.

Yes, it sounds fairly formal and instructional.

It feels like something you might see in:

• a postal service notice
• a tracking page
• a form or system message
• an official instruction

That matches the vocabulary choices, especially kumpirmasyon, subaybayan, and rehistradong koreo.
