wǒ juéduì tóngyì.

Because 绝对 is functioning as an adverb here, and adverbs in Mandarin usually go before the verb they modify.

So the structure is:

我 + 绝对 + 同意
I + absolutely + agree

This is very similar to English absolutely agree, except in Mandarin the word order is more strictly adverb-before-verb.

In 我绝对同意, 绝对 is an adverb, meaning absolutely.

It can also be used as an adjective in other contexts, for example to mean absolute. But in this sentence, it modifies 同意, so it works like an adverb.

Yes. 我同意 is completely natural and means I agree.

Adding 绝对 makes the agreement stronger:

• 我同意 = I agree
• 我绝对同意 = I absolutely agree / I totally agree

So 绝对 adds emphasis.

Yes, it is natural, especially when you want to sound very certain or emphatic.

That said, in casual conversation, native speakers might also say things like:

• 我完全同意 = I completely agree
• 我非常同意 is less natural
• 我很同意 is usually not correct

So 绝对同意 and 完全同意 are both good choices for strong agreement.

Because 同意 is generally not the kind of verb that is naturally modified by 很 in this way.

In Mandarin, 很 often works well with adjectives, but not every verb can take it naturally. For agreeing strongly, Mandarin prefers adverbs like:

• 很同意 → usually unnatural
• 非常同意 → possible in some contexts, but less common
• 完全同意 → natural
• 绝对同意 → natural

So for this sentence, 绝对 is a much better choice than 很.

Not always. 同意 can be used by itself when the thing you agree with is already understood from context.

For example:

• 我绝对同意。 = I absolutely agree.
• 我绝对同意你的看法。 = I absolutely agree with your opinion.
• 我同意这个决定。 = I agree with this decision.

So in your sentence, the object is simply omitted because it is already clear.

Yes. In Mandarin, 同意 can work in ways that cover both English agree and agree with, depending on the structure.

Examples:

• 我同意。 = I agree.
• 我同意你。 = I agree with you.
  This is understandable, though 我同意你的看法 is often more precise.
• 我同意这个计划。 = I agree with this plan.

So English may require different wording, but Mandarin often uses the same verb.

It is pronounced juéduì.

Tone by tone:

• 绝 = second tone (jué)
• 对 = fourth tone (duì)

A rough pronunciation guide for English speakers:

• jué sounds somewhat like jweh
• duì sounds somewhat like dway, but shorter and tighter

Be careful not to flatten the tones. The rise in jué and the sharp fall in duì help it sound natural.

Both mean strong agreement, and both are natural.

A useful way to think about the difference:

• 绝对同意 = absolutely agree
• 完全同意 = completely agree

In many situations, they are interchangeable.
But 绝对 often feels a little more forceful or emphatic, while 完全 can feel slightly more neutral or formal.

Yes, especially in conversation.

Mandarin often omits the subject when it is obvious from context. So if someone says something and you respond:

• 绝对同意！

that sounds like Absolutely agree! or Totally agree!

Including 我 makes the sentence more complete, but omitting it is very common in speech.

It is fairly neutral. It can work in both spoken and written Mandarin.

• In conversation, it sounds emphatic but natural.
• In writing, it is still fine, especially in comments, messages, or discussions.

If you want something more formal, you might expand it:

• 我完全同意这个观点。 = I completely agree with this viewpoint.
• 我对此表示完全同意。 = I express complete agreement with this.

But 我绝对同意 itself is not inappropriate; it is just direct and strong.

Yes. You can say:

• 是的，我绝对同意。

This means Yes, I absolutely agree.

Adding 是的 makes it sound a little more explicit as a response. Without it, 我绝对同意 is already a complete and natural reply.

Because Mandarin often does not need a separate preposition where English uses with.

English says:

• I agree with you
• I agree with this idea

Mandarin usually just uses 同意 + person/idea/opinion directly:

• 我同意你。
• 我同意这个想法。
• 我同意你的意见。

So the relationship is built into the verb 同意, and no extra word for with is usually necessary.

Sometimes, yes. 绝对 is very strong. It suggests certainty and strong support.

That is perfect when you really want emphasis, but if the situation is more cautious, you might choose a softer expression such as:

• 我同意。 = I agree.
• 我比较同意。 = I rather agree / I mostly agree.
• 我基本上同意。 = I basically agree.

So 我绝对同意 is best when you want a clear, confident statement.
