What is the interjection "aw" in Esperanto?

Question

I'm looking for an interjection to express sympathy or dissapointment, or in response to something sweet.

I first thought of aŭ , but apppart from being a conjuction I recently learned that can be used to express pain.

Looking through the suggested sources of this question gave no result:

Is there a standard reference to learn interjections?

Answer 1

For sympathy or disappointment, I would say Ho ve and then some other words of sympathy like Mi bedaŭras aŭdi tion.

For something cute - why not ho! tre ĉarme! ?

For pain aj is much more common.
