Which is more correct to say in a question? (For example a guy that wakes up in a train)

"Where am I?"

or

"Where I am?"


Solution 1:

If you don't know where you are, you ask, "Where am I?"

The only legitimate use for "Where I am?" is in response to a question about the location of something that you think might be occupying the same general space you are. For example,

Questioner: Do you know where your clothes are?

You: Where I am?

Questioner: Wrong. We found you running around the streets nude.

Solution 2:

The point of difficulty is in recognizing that a form of be can function as an auxiliary verb. Questions in English are formed via Subject-Auxiliary Inversion. If the finite verb in a declarative sentence is any of the following (called auxiliary verbs):

do
be
can
may
shall
will
have

the corresponding question is formed by placing a question word (if it's a content question) at the beginning of the sentence, and then placing the auxiliary verb after the question word (if any). Then put in the rest of the sentence (with the original auxiliary verb and the antecedent of the question word omitted).

For example:

Thomas will buy [beets].
Will Thomas buy beets?
[What] will Thomas buy?

Thomas is [at school].
Is Thomas at school?
[Where] is Thomas?

Thomas should buy beets [at the store].
Should Thomas buy beets at the store?
[Where] should Thomas buy beets?

For declarative sentences whose finite verb is not among the auxiliaries, for the purpose of forming a question you treat the sentence as if it contained an auxiliary do. For example.

Thomas went [to the store]. (original declarative)
Thomas did go [to the store]. (effective form for the purposes of question formation)
Did Thomas go to the store?
[Where] did Thomas go?
