Would you say that both of the following versions are acceptable in all versions of English? I'm aware that grammar books prefer the second one.

1- Don't you know who am I?

2- Don't you know who I am?

Many thanks to all of you! I appreciate your time and effort.

I needed light on "Do you know who am I?" because:

So, I really need more light on the topic please.

Hi Tom,
I am not sure exactly why such a well-known reference would validate this usage. It is puzzling to me. Unless I am wrong all along myself.

The only way for this question to be correct will be putting it in quotes:
She asked me " who was the best player ....?".

To my knowledge, the " Wh" words should not be placed right next to the verb in indirectly questions. e.g. Do you know what time it is ? [ Not what is the time ?]

The following links explain in more details:

Unit 66 - Indirect Questions

Indirect questions are polite, longer forms of normal questions. For example:
- Where's the department store? - Direct question
- Could you tell me where the department store is, please? - Indirect question
- What's his name? - Direct question
- Do you know what his name is? - Indirect question

Mr. TomSo, I really need more light on the topic please.

1. Swan's examples do not include "where", so "wondered where was" is not a combination he makes any claims for in this section of his book. His example is "wondered which was". The rule will definitely not work for anything that can't be a subject of a sentence, so it has to be restricted to the three words Swan mentions specifically.

2. All his examples are reported questions. "Do you know?" does not report a question, so all your examples with "Do you know?" are outside the bounds of the combinations Swan is talking about in this section of his book. (I'm not sure this is relevant, however, as it seems to me that this rule should apply more broadly than stated here.)

3. He gives only examples of third person nouns -- no pronouns: the best player, the matter, her seat. Given only this page of his book, it's not possible to prove that he meant to exclude pronouns, but in my opinion, he did intend to exclude them. She asked who was he is clearly ungrammatical to my ear. You would have to have more than just a pronoun in that position: She asked them who was the leader of the group. (Even this is a bit suspect in my opinion.)

I'm simply grateful to you people for putting in so much effort on my behalf!

Leaving Swan aside for a moment, I'd like to know how this sentence sounds to native ears - do they cringe? Or do you find it acceptable?

She asked me what was the matter.

She asked me what the matter was -is the way I would say it. However your version sounds Ok to me just a bit awkward.

Uuuh! I am not a native and I can't speak for those who are. I don't go as far as cringing, but when I hear someone say this, it tells me something about the person's acadamic background. People who are well educated usually have a higher level of langauge command.
Mr. TomShe asked me what was the matter.
This does not match that description, to me anyway.Emotion: smile
Mr. TomShe asked me what was the matter.
"the matter" is idiomatic for "wrong", "amiss", so I find this sentence just as good as "She asked me what was wrong."

The idiom "What is the matter" has been discussed on this forum ad infinitum. See what is the matter.
