Da của tôi hơi đau.

Da means skin.

In Da của tôi hơi đau, it refers to the speaker’s skin in general. Vietnamese does not need an article like the or my directly before da. Possession is shown separately with của tôi.

Của tôi means of mine / my.

So:

• da = skin
• của tôi = my
• da của tôi = my skin

This is a clear, correct way to show possession. However, in everyday Vietnamese, people often say da tôi instead of da của tôi, especially with body parts.

So both are understandable, but:

• Da của tôi hơi đau = correct, a bit more explicit
• Da tôi hơi đau = more natural in casual speech

Yes — and in many situations, Da tôi hơi đau sounds more natural.

Vietnamese often leaves out của when talking about things closely associated with a person, especially:

• body parts
• family members
• personal belongings in obvious contexts

So a native speaker will often prefer:

• Tay tôi đau. = My hand hurts.
• Mắt tôi đau. = My eye hurts.
• Da tôi hơi đau. = My skin hurts a little.

Using của is not wrong; it just sounds a little more formal, emphatic, or textbook-like here.

Hơi means a little, slightly, or somewhat.

It softens the statement:

• Da của tôi đau. = My skin hurts.
• Da của tôi hơi đau. = My skin hurts a little.

It is very common in Vietnamese for describing mild states:

• hơi mệt = a little tired
• hơi lạnh = a little cold
• hơi buồn = a little sad

Because Vietnamese often puts the description or state after the noun.

So the structure is basically:

• Da của tôi = my skin
• hơi đau = hurts a little / is a little painful

Literally, it is something like:

My skin a-little painful

This is normal Vietnamese word order. The thing being described comes first, and the condition comes after.

It can be thought of as a state word. In English, we might translate it with a verb (hurts) or an adjective (painful), depending on what sounds natural.

In this sentence, đau describes the condition of the skin. So:

• Da tôi đau. = My skin hurts. / My skin is painful.

Vietnamese does not always divide words into parts of speech in exactly the same way English does, so it is often best to learn đau as a word meaning to hurt / painful depending on context.

Yes, it is understandable and correct. But depending on the situation, a native speaker might choose a slightly different sentence.

Commoner or more natural versions might be:

• Da tôi hơi đau. = My skin hurts a little.
• Da tôi hơi rát. = My skin stings/burns a little.
• Da tôi hơi ngứa. = My skin is a little itchy.

If the skin pain is more like soreness, burning, or irritation, a more specific word may sound better than đau.

So Da của tôi hơi đau is fine, but in real life the best word depends on the exact feeling.

These words describe different sensations:

• đau = hurt, pain
• rát = burning/stinging, like after sunburn or irritation
• ngứa = itchy

For skin, native speakers often use:

• Da tôi bị ngứa. = My skin is itchy.
• Da tôi hơi rát. = My skin stings a little.
• Da tôi đau. = My skin hurts.

So if you mean general pain, đau works. But if you mean a more specific skin sensation, another word may be better.

Usually not in this sentence if you want to clearly say my skin.

You need something to show whose skin it is:

• Da hơi đau. = The skin is a little painful / Skin hurts a little.

This could work only if the context already makes it obvious whose skin you mean, but by itself it sounds incomplete or vague in many situations.

So normally you would say:

• Da tôi hơi đau.
• Da của tôi hơi đau.

Vietnamese often does not use a verb like to be in sentences describing a state.

In English:

• My skin is a little painful.

In Vietnamese:

• Da tôi hơi đau.

There is no need for là here. In fact, là would be wrong in this kind of sentence.

Use là mainly when equating one thing with another:

• Tôi là giáo viên. = I am a teacher.

But for conditions and descriptions:

• Tôi mệt. = I am tired.
• Da tôi hơi đau. = My skin hurts a little.

A rough pronunciation guide is:

• Da = like za in northern Vietnamese, more like ya in many southern accents
• của = roughly koo-uh with a dipping/creaky tone on củ
• tôi = roughly toy
• hơi = roughly huh-ee / huhi with the hơi tone kept low-falling
• đau = roughly dow with a level tone

A few important notes:

• đ is not the same as d
• d, gi, and r vary by dialect
• tones matter a lot, especially in của, hơi, and đau

If you are learning a specific dialect, pronunciation may differ somewhat.

You can use không before đau:

• Da tôi không đau. = My skin doesn’t hurt.

If you want to keep hơi, that usually does not combine naturally with a simple negative in the same way. You would normally say one or the other depending on meaning:

• Da tôi hơi đau. = My skin hurts a little.
• Da tôi không đau. = My skin doesn’t hurt.

A common way is to add a question particle such as không or à:

• Da tôi hơi đau, có sao không? = My skin hurts a little, is that okay?
• Da tôi hơi đau à? = My skin hurts a little?
• Da tôi có hơi đau không? = Does my skin hurt a little?

If you are asking someone else about their skin, you would change the pronoun:

• Da bạn có hơi đau không? = Does your skin hurt a little?

Usually, Tôi đau da is not the most natural way to say this.

Vietnamese usually expresses pain in body parts by making the body part the topic:

• Da tôi đau.
• Tay tôi đau.
• Lưng tôi đau.

So for skin, Da tôi hơi đau sounds much better than Tôi đau da.

Sometimes you may hear patterns with bị:

• Tôi bị đau da can be understood, but it often sounds less natural or less specific than Da tôi đau or Da tôi bị kích ứng depending on context.

For a learner, the safest natural pattern is:

[body part] + [possessive] + đau

For example:

• Mắt tôi đau.
• Cổ tôi đau.
• Da tôi hơi đau.
