Mainit pa ang tubig sa gripo.

In Filipino, it is very common to begin a sentence with the predicate, not the subject. Here, mainit means hot, and it comes first because the sentence is structured like:

Mainit + ang tubig sa gripo
= The tap water is hot

So the word order is closer to Hot is the water in the faucet than to normal English word order. This is completely natural in Filipino.

Pa means still in this sentence.

So Mainit pa means still hot.

It often shows that a condition continues:

• Mainit pa = still hot
• Bukas pa = still open / not closed yet
• Nandito pa = still here

In other contexts, pa can also mean something like more or yet, but here the best meaning is still.

Ang marks the subject or topic of the sentence.

In Mainit pa ang tubig sa gripo, the thing being talked about is ang tubig sa gripo = the water from the faucet / tap water.

So:

• mainit = predicate
• ang tubig sa gripo = subject/topic

Without ang, the sentence would sound incomplete or ungrammatical in standard usage.

Sa gripo means in the faucet, from the faucet, or more naturally in English here, tap / from the tap.

So:

• sa = a location/direction marker, often meaning in, at, to, or sometimes from depending on context
• gripo = faucet / tap

In this sentence, tubig sa gripo refers to water in/from the faucet, which English usually expresses as tap water.

Gripo means faucet or tap.

It is a common everyday word in Filipino. Depending on the variety of English:

• American English: faucet
• British English: tap

So tubig sa gripo is essentially water from the tap or tap water.

There is no separate word for is here. In Filipino, sentences like this often do not use a linking verb the way English does.

So:

• Mainit pa ang tubig sa gripo. literally works like
• Still hot the tap water.

But in natural English, we translate it as:

• The tap water is still hot.

This is very normal in Filipino adjective-based sentences.

It is best understood here as an adjective meaning hot, but in Filipino, words like this can function as predicates without needing a separate verb.

So in English grammar terms, you might think:

• mainit = adjective

But in Filipino sentence structure, it behaves as the main predicate of the sentence:

• Mainit ang tubig. = The water is hot.

That is why it can appear at the beginning and carry the main descriptive meaning.

Yes. Ang tubig sa gripo ay mainit pa is also correct.

That version puts the subject first:

• Ang tubig sa gripo = the tap water
• ay = linker/topic marker
• mainit pa = still hot

So you have two common patterns:

• Mainit pa ang tubig sa gripo.
• Ang tubig sa gripo ay mainit pa.

Both mean the same thing. The first one is often more conversational and very common.

Because sa gripo expresses location/source better here.

• tubig sa gripo = water in/from the faucet, tap water
• tubig ng gripo would sound more like the faucet's water, which is less natural

In Filipino, sa is often used where English would use in, at, from, or where English turns something into a noun modifier like tap water.

Yes, that is exactly the kind of nuance pa often gives.

The sentence suggests continuation:

• the water was hot before
• it remains hot now

So it naturally implies The tap water is still hot, often with the sense that someone expected it to cool down or change.

Without pa, it simply means:

The tap water is hot.

With pa:

• Mainit pa ang tubig sa gripo.
• The tap water is still hot.

So pa adds the idea of continuation.

Yes, it is a very natural way to say tap water.

Word-for-word, it is something like water from the faucet/tap, but in ordinary English the best translation is often just tap water.

So even though the Filipino structure is different, learners can remember:

• tubig sa gripo = tap water
