Tim của tôi đau.

• tim = heart
• của = a word that shows possession, like of or 's
• tôi = I / me / my
• đau = hurt / painful / ache

So the structure is literally something like heart of me hurts, which corresponds to My heart hurts in natural English.

In Vietnamese, the possessed thing usually comes first, and the owner comes after it.

So:

• tim của tôi = my heart
• literally: heart of me

This is different from English, where my comes before the noun.

A very common pattern is:

• noun + của + person

Examples:

• nhà của tôi = my house
• sách của Lan = Lan's book
• xe của anh ấy = his car

của marks possession. It links tim and tôi so that the phrase means my heart.

Think of it as similar to:

• of in the heart of me (literal idea)
• or 's in my heart / Lan's book

So:

• tim của tôi = my heart
• tim của anh ấy = his heart

Yes — and in many cases, tim tôi đau sounds more natural and less formal than tim của tôi đau.

Vietnamese often omits của when the relationship is obvious, especially with body parts, family terms, and everyday possession.

So both are understandable:

• Tim của tôi đau.
• Tim tôi đau.

But Tim tôi đau is usually more natural in normal speech.

It is understandable and grammatical, but it can sound a bit explicit or stiff in everyday conversation.

For body parts, Vietnamese speakers often prefer:

• Tim tôi đau.
• or depending on context, something more idiomatic like Tôi đau tim or Tôi bị đau tim.

Be careful, though: different expressions can suggest slightly different things:

• Tim tôi đau = My heart hurts
• Tôi đau ở tim = I have pain in my heart / heart area
• Tôi bị đau tim can sound more like I have heart trouble / a heart condition / heart pain

So your sentence is fine for learning the structure, but in real conversation another phrasing may be more common.

Vietnamese often does not need a verb like to be where English does.

Here, đau works like a stative verb or adjective meaning hurt / painful.

So:

• Tim của tôi đau literally = My heart hurts not
• My heart is hurt in the English grammar sense

This is very common in Vietnamese:

• Tôi mệt. = I am tired.
• Anh ấy buồn. = He is sad.
• Chân tôi đau. = My leg hurts.

No separate word for is is needed.

It behaves somewhere between the two from an English learner's point of view.

In this sentence, đau means to hurt / to ache / painful. Vietnamese words often do not fit neatly into English-style categories.

So:

• Tim tôi đau = My heart hurts
• Tay tôi đau = My arm hurts
• Đau quá! = It hurts so much!

For learning purposes, it is often easiest to think of đau here as hurt / ache.

It can be both, depending on context.

• Physical/anatomical: tim = heart
• Emotional/poetic: tim can also refer to the emotional heart

Vietnamese also often uses trái tim, especially in poetic or expressive language.

Examples:

• tim = plain everyday heart
• trái tim = also heart, sometimes more literary or emotional

In Tim của tôi đau, the most likely reading is physical pain unless the context is poetic or emotional.

Both mean heart.

• tim is shorter and very common in everyday speech
• trái tim can sound a little fuller, more expressive, or more literary

Examples:

• Tim tôi đau. = My heart hurts.
• Trái tim tôi đau. = also My heart hurts, but it may sound more emotional or poetic depending on context

In medical or ordinary conversation, tim is very common.

A rough pronunciation guide for English speakers:

• tim ≈ teem
• của ≈ roughly koo-uh, with a dipping/rising tone
• tôi ≈ roughly toy (but not exactly English toy)
• đau ≈ roughly dow (like the start of down without the final n)

Very roughly:

• teem koo-uh toy dow

Important note: Vietnamese tones matter a lot, so this English approximation is only a starting point.

The tones are:

• tim — level tone
• của — hỏi tone
• tôi — level tone
• đau — level tone

So only của has a marked tone here. The others are unmarked for tone.

If you're learning pronunciation, của is probably the trickiest word in the sentence.

Not normally in ordinary speech.

Tim của tôi đau is more literal: My heart hurts.

If you want to express emotional heartbreak, Vietnamese usually uses clearer emotional wording, for example:

• Tôi đau lòng. = I am heartbroken / I feel hurt inside
• Tim tôi tan vỡ. = My heart is broken (more literary/dramatic)

So without special context, learners should understand Tim của tôi đau as physical or literal pain.

You can put không before đau:

• Tim của tôi không đau. = My heart doesn't hurt.

More natural variants:

• Tim tôi không đau.
• Tim tôi không bị đau.

The basic pattern is:

• noun phrase + không + đau

A simple yes/no question is:

• Tim của tôi đau à? = Does my heart hurt?
• Tim tôi đau hả? = Does my heart hurt? / My heart hurts?

You could also ask more directly in conversation:

• Tim tôi có đau không? = Does my heart hurt?

The exact form depends on style and context, but all of these are possible question patterns in Vietnamese.

Yes. This is a very useful pattern.

Pattern:

• [body part] + (của) + [person] + đau

Examples:

• Đầu tôi đau. = My head hurts.
• Tay tôi đau. = My arm/hand hurts.
• Chân tôi đau. = My leg hurts.
• Mắt tôi đau. = My eye hurts.

Again, in everyday speech, Vietnamese often drops của:

• Đầu của tôi đau → understandable
• Đầu tôi đau → more natural
