Pareho ba kayong pupunta sa bangko, o si Ana lang ang pupunta?

In this sentence, pareho means both.

The word pareho can also mean the same in other contexts, but here it is asking whether the two people being addressed are both going to the bank, as opposed to only Ana going.

Ba is the yes/no question particle in Filipino. It usually comes after the first word or phrase that the speaker is highlighting.

So:

• Pareho ba kayong pupunta...? = Are both of you going...?
• Pupunta ba kayo...? = Are you going...?

Here, the speaker puts pareho first to emphasize the contrast between both of you and only Ana.

Kayong is kayo plus the linker -ng.

• kayo = you (plural, or sometimes polite singular)
• -ng links kayo to the following word, here pupunta

So kayong pupunta means something like you who will go or more naturally you going.

This linker is very common in Filipino:

• akong aalis = I who will leave / I’m the one leaving
• silang darating = they who will arrive
• kayong pupunta = you who will go

Without the linker, this structure would sound unnatural.

Yes. In this sentence, kayo clearly refers to more than one person, and because of pareho, it specifically means both of you.

It is true that kayo can sometimes be used as a polite way to address one person, but that is not possible here, because pareho requires at least two people.

Pupunta is in the contemplated/future aspect.

It comes from the verb punta / pumunta, meaning to go. In context, pupunta can be translated as:

• will go
• are going to go
• sometimes simply are going, depending on context

So here it refers to a future or intended action.

Sa is a marker used for locations and destinations.

With a motion verb like pupunta, sa usually means to:

• pupunta sa bangko = going to the bank

In other contexts, sa can also mean in, at, or on, depending on the sentence.

Lang means only or just.

It usually comes after the word or phrase it limits. So:

• si Ana lang = only Ana
• ikaw lang = only you
• ngayon lang = only now / just now

In your sentence, si Ana lang means that Ana is the only person who will go.

The fuller pattern X ang pupunta is very natural in Filipino and means X is the one who will go.

So:

• si Ana lang ang pupunta = Only Ana is the one who will go

Here:

• si marks Ana as a personal name
• ang pupunta means the one who will go

This is an identifying structure. A helpful comparison is:

• Ang pupunta ay si Ana lang.
• Si Ana lang ang pupunta.

Both mean the same thing. The version in your sentence is the more natural conversational order.

Filipino often repeats the verb or predicate for clarity, especially in A or B questions.

So this is very natural:

• Pareho ba kayong pupunta sa bangko, o si Ana lang ang pupunta?

A shorter version is also possible in casual speech:

• Pareho ba kayong pupunta sa bangko, o si Ana lang?

But the repeated ang pupunta makes the contrast extra clear.

Yes. A natural alternative is:

• Pupunta ba kayong pareho sa bangko, o si Ana lang ang pupunta?

This means basically the same thing.

The original sentence puts pareho first, which gives a little more emphasis to the idea of both of you. So the original sounds especially good when the speaker is contrasting:

• both of you vs.
• only Ana

In a sentence like this, yes, pareho normally implies two people: both.

If you were talking about more than two people, you would usually use something like lahat for all instead.

So here, the sentence strongly suggests that the speaker is talking to two people and asking whether both are going, or only Ana.
