wǒ dǒng tā de huà.

的 links 他 and 话 and shows a relationship like possession or association.

So:

• 他 = he / him
• 话 = speech, words, what someone says
• 他的话 = his words, what he says, or his speech

In English, this is often like his in his words.

Because 懂 here is about understanding words/speech/content, not just understanding a person in a broad emotional or personal sense.

• 我懂他的话。 = I understand what he says / I understand his words.
• 我懂他。 = I understand him.

Both are possible, but they mean slightly different things.

In this sentence, 话 means words, speech, or what someone says.

It does not mean just a single isolated word in the dictionary sense. It is more like:

• someone’s way of speaking
• someone’s words
• what someone said

So 他的话 is very naturally understood as what he says or his words.

Yes, it is grammatical and understandable.

It sounds natural in contexts like:

• someone is hard to understand, but I can understand him
• someone speaks in a certain dialect/style, and I understand it
• you want to say you understand what he means

That said, in everyday speech, Mandarin speakers might also say:

• 我听得懂他说的话。 = I can understand what he says when I hear it.
• 我懂他说的话。 = I understand what he says.

These can sound a bit more specific or more common depending on context.

This is a very common question.

• 懂 = to understand, to grasp the meaning
• 听懂 = to understand what you hear

So:

• 我懂他的话。 focuses on understanding his words/meaning.
• 我听得懂他的话。 focuses on being able to understand him when listening.

If the issue is spoken comprehension, 听懂 is often more precise.

Yes.

Mandarin often allows this kind of flexibility. Depending on context, 他的话 can mean:

• his words
• what he says
• what he said
• his speech

Chinese does not always mark tense the way English does, so context decides whether it is present or past.

In most everyday Mandarin, 的 is usually pronounced with a neutral tone: de.

So:

• 我 wǒ
• 懂 dǒng
• 他 tā
• 的 de
• 话 huà

This light pronunciation is normal. Learners should avoid stressing 的 too much unless there is a special reason.

Normally, no.

他的话 is the standard form. Without 的, 他话 sounds incomplete or unnatural in this sentence.

There are some cases in Chinese where 的 can be omitted in noun phrases, but this is not a good example of that. For a learner, it is safest to keep 的 here.

In spoken Mandarin, 他 tā and 她 tā are pronounced the same: tā.

So when you hear the sentence, it could mean:

• he
• she

In writing, this sentence uses 他, which usually means he. But in speech, you need context to know which one is meant.

The structure is:

我 + 懂 + 他的话

or:

subject + verb + object

More specifically:

• 我 = subject
• 懂 = verb
• 他的话 = object

This is a very typical Mandarin word order: Subject–Verb–Object.

Sometimes, yes, depending on context.

If someone speaks in a certain dialect, accent, or style, 他的话 could refer to the speech coming from him, so the sentence could be understood as I understand the way he speaks.

But if you specifically want to say I understand his language, Mandarin would often use a clearer expression, such as one referring directly to the language or dialect.

So the most natural default meaning is still I understand what he says.

A natural pronunciation is:

Wǒ dǒng tā de huà.

A few pronunciation notes:

• wǒ = 3rd tone
• dǒng = 3rd tone
• tā = 1st tone
• de = neutral tone
• huà = 4th tone

When speaking naturally, the first two 3rd tones in wǒ dǒng are affected by normal connected speech, but learners do not need to worry too much at first. Just make sure:

• wǒ is not flat
• dǒng is clear
• de is light
• huà is sharp and falling

Sometimes, yes, but the nuance is a little different.

• 懂 often means understand, know, or be able to make sense of
• 明白 often emphasizes clear understanding

So:

• 我懂他的话。 = I understand what he says.
• 我明白他的话。 = I understand his words clearly / I get what he means.

Both can work, but 懂 is very natural here.
