XY/XXYY(/XYXY) has nothing different on meaning. emphasizing or not has nothing to do with meaning either. but sometimes XYXY may be used as predicate, which is the BIGGEST different, but you missed this point

Nobody says they have different meaning, I was trying to tell the difference between repeating and nonrepeating. Repeating do express the strong feeling of the speaker or writer. In China, even a child knows to use the trick to express emotion. e.g. "妙妙，你今天玩得开心吗？", "非常非常非常非常不开心！". The more repeating 非常, the stronger feeling she wants to express.

As adj./adv., XXYY/XYXY has grammar different after all. But XXYY/XYXY could be used as (just AS, but they are not verb. Chinese, natively, has no concept of part of speech) verb, with different meaning. Meanwhile XY sometimes has no such usage.

<p>I do believe there is a differential meaning in multiplied words. One important meaning is that to repeat a word or phrase in the AABB manner is to impose a fictive duration upon AB. For example, we can speak 热闹一下，but not *热热闹闹一下 because 热热闹闹 denotes a duration reading that is incompatible with the perfect meaning expressed by '一下'. </p>

I don't think Chinese, natively, has meaning of part of speech like English. In traditional learning of Chinese, there was no study about grammar, which started in no earlier than Tang Dynasty. The modern grammar theory of Chinese is only for foreigners to learn, but natives never care about that. So you may feel Chinese has many grammar rules, and even more exceptions of each rule. In Chinese a noun may take the place of adj., or even verb. That's not multiple parts of speech, but just because Chinese never have concept of part of speech, which should be from western linguistic

As a native Chinese speaker, I've never learned the AABB "grammar rule" from book. This means it's never considered as a kind of grammar rule at least in my student age.

But I don't agree with @gcd0318. There is difference between AB and AABB. In Chinese, repeating usually means emphasize the AB word, or to make the sentence sounds good to phonology.

e.g. 勤恳（diligent and conscientious） vs. 勤勤恳恳
Although they have the same mean, but use 勤勤恳恳 always make the audience feel that the speaker is highly applaud one's diligent and conscientious. Use 勤恳 doesn't have the strong emotional feeling.

Back to your example, 热热闹闹, it's the same as usage of 勤勤恳恳. It emphasize how bustling it is.
