Do you know who am I? or do you know who I am?

Question

What is correct to say; and why if somebody can explain me I'll appreciate it .

Answer 1

Do you know who I am?
And..er no, sorry I dont!

Answer 2

Goddess of grammar and Persian girl are right. The question is whether you know what an embedded sentence/clause or an indirect question is. If not, you're in trouble here. First of all, an embedded or subordinate clause or sentence is one which is part of a larger sentence. So:
Who am I? is not embedded/subordinate but [who I am] as part of Do you know [who I am]? is. Does this make sense? If not please post a follow-up question. Second, as a GENERAL rule the inversion of subject and verb in questions in English occurs only in main (i.e., non-embedded, non-subordinate) sentences/clauses. Third, there are exceptions to this rule. One is that when you are quoting someone's words exactly (direct speech, direct quotation), then you keep them as they are. So if someone said "Who am I?" you can report "John asked me, "Who am I?""". So in that case you do keep the inversion despite the embedding. Does this make sense? Again, if not, please post follow-up.

Also, like most rules of English grammar, all this is not something made up by someone, but is a feature that is shared by many many languages. No one knows precisely why languages have such rules, and even worse why (if many languages do, why they do not all do it), but there is considerable research heading towards an answer. Some aspects of this appear to be innate, i.e., inborn. That at any rate is what Noam Chomsky from MIT and his followers claim.

Answer 3

The correct sentence is "Do you know who I am?" In English, yes-no questions are formed by moving the main auxiliary verb (verbs like "be", "have", and "do" of a sentence to the beginning. In the sentence you're trying to say, you're basically working with the the sentence "You know who I am". In the main verbal construction, there is no auxiliary verb ("am" is not a main verb, but part of a secondary phrase), so you have to insert the dummy verb "do": "You do know who I am", which is then moved to the front to get the sentence "Do you know who I am?"

Answer 4

Unfortunately in English, when you're turning a sentence into a question, the word order differs a little bit.

(Unlike Spanish or Persian/Farsi...)

the correct way to say is "Do you know who I am?"

Answer 5

The correct way is Do you know who I am. Ask your English teacher!

Answer 6

"Do you know who I am?" is generally correct. If you're trying to have a guessing game, where you give clues to someone's identity, you could title it "Who Am I?" When you put it into the context of a regular sentence, though, you need to say "Do you know who I am?"

Answer 7

Technically, both are correct. In actual practice, unless your writing poetry, or trying to sound exotic, or showing off your sentence construction skills - use the later. It makes you sound more natural and personable.

Answer 8

COrrect to say is "Do you know who I am?" Do you know who am I, just doesn't make sense. Another acceptable wording is, "You probably don't know me, but you look familiar.". And even though it's more confusing, and semi accepted, another way is "Who Am I?".

Answer 9

do u know who i am? is correct.because u are asking an indirect question.in indirect questions,u should ask like this.e.g."can u tell me what the meaning is?"or "i can't remember what his name is?"u have to change the position of the subject and the verb and it shouldn't be like an ordinary question.the other one,"do u know who am i?", is completely wrong.

Answer 10

Do you know who I am?
In imbedded questions, the subject comes before the verb.

Answer 11

"Do you know who I am?" is the correct one.
You have to change the position of the subject and the verb when you form such a question..

You say: "Who am I?" but "Do you know who I am" and for example "Where is she?" BUT "Do you know where she is?" etc..
