Masakit ang bibig ko dahil mainit ang kape.

In Filipino, a separate verb like is/are is usually not needed in simple descriptive sentences.

So:

• Masakit ang bibig ko = My mouth is sore / hurts
• Mainit ang kape = The coffee is hot

Filipino often just puts the description first and the thing being described after it.

Because Filipino commonly uses a predicate-first word order.

So instead of saying:

• My mouth is sore

Filipino naturally says something closer to:

• Sore the mouth my

That gives:

• Masakit ang bibig ko

This is normal and very common. English usually starts with the subject, but Filipino often starts with the predicate or description.

Masakit means painful, hurting, or sore, depending on context.

In this sentence, Masakit ang bibig ko most naturally means:

• My mouth hurts
• My mouth is sore

It comes from the root sakit, which is related to pain or illness.

Examples:

• Masakit ang ulo ko. = My head hurts.
• Masakit ang lalamunan ko. = My throat hurts.

Ang is a very important marker in Filipino. It marks the noun that is the topic or the main noun being talked about in that part of the sentence.

So:

• Masakit ang bibig ko
  = the thing being described as painful is ang bibig ko
• Mainit ang kape
  = the thing being described as hot is ang kape

You do not translate ang directly as the every time, even though it can sometimes feel similar in English. Its job is grammatical, not just definite article marking.

Ko here means my, but grammatically it is a genitive pronoun that usually comes after the noun it possesses.

So:

• bibig ko = my mouth
• ulo ko = my head
• kamay ko = my hand

This is a normal Filipino pattern:

• noun + possessor

Examples:

• bahay ko = my house
• kaibigan ko = my friend

So ang bibig ko literally looks like the mouth my, but naturally means my mouth.

Dahil means because.

It connects the two ideas:

• Masakit ang bibig ko = My mouth hurts
• dahil mainit ang kape = because the coffee is hot

So the whole sentence means:

• My mouth hurts because the coffee is hot

Dahil introduces a reason or cause.

Another example:

• Umuwi ako dahil pagod ako.
• I went home because I was tired.

Again, this is because predicate-first order is very common in Filipino.

So the most natural everyday pattern is:

• Mainit ang kape. = The coffee is hot.

You can also say:

• Ang kape ay mainit.

This version is also correct, but it sounds more structured, emphatic, or sometimes a bit more formal/written, depending on context.

In casual speech, mainit ang kape is very normal.

Yes, that is grammatically correct.

Compare:

• Masakit ang bibig ko dahil mainit ang kape.
• Ang bibig ko ay masakit dahil mainit ang kape.

Both are correct. The first one is more natural in ordinary Filipino because it follows the common predicate-first pattern. The second one uses ay, which creates a more subject-first arrangement.

So:

• Masakit ang bibig ko = more usual in everyday speech
• Ang bibig ko ay masakit = also correct, but less conversational

Bibig usually means mouth.

In some contexts, people may loosely use it in a way that can overlap with lips, but the basic meaning is mouth.

So in this sentence, Masakit ang bibig ko most likely means:

• My mouth hurts
• or possibly My mouth is sore/burned

If you specifically want to say lips, Filipino often uses labi.

That is the most likely idea, yes.

The sentence literally says:

• My mouth hurts because the coffee is hot.

In real-life context, that strongly suggests the coffee was hot enough to hurt or burn the speaker's mouth.

So even if the exact English translation shown to the learner is simple, the implied meaning is probably something like:

• My mouth hurts because the coffee was too hot.
• I burned my mouth because the coffee was hot.

But the Filipino sentence itself does not explicitly say too hot or burned. It just states the pain and the reason.

No. A very common alternative is kasi.

For example:

• Masakit ang bibig ko kasi mainit ang kape.

That also means:

• My mouth hurts because the coffee is hot.

The difference is mostly tone:

• dahil can sound a bit more neutral or formal
• kasi is very common in casual speech

Both are useful, but kasi is especially common in conversation.

A simple pronunciation guide:

• masakit = ma-sa-kit
• bibig = bi-big
• ko = ko
• dahil = da-hil
• mainit = ma-i-nit
• kape = ka-pe

A few helpful notes:

• Filipino words are usually pronounced clearly syllable by syllable.
• ng in Filipino is its own sound, like the ng in sing.
• Stress matters in Filipino, though beginners can first focus on getting the syllables right.

If you say the sentence slowly:

• Ma-sa-kit ang bi-big ko da-hil ma-i-nit ang ka-pe

you will already sound much closer to natural Filipino pronunciation.

You can try, but it will sound unnatural in English.

A very literal breakdown is:

• Masakit = painful / hurts
• ang bibig ko = my mouth

So the structure is roughly:

• Painful/hurting my mouth

But natural English would be:

• My mouth hurts
• My mouth is sore

So it is better to understand the Filipino structure on its own instead of forcing it into English word order.
