'Why has it been removed' or 'why it has been removed'? [duplicate]
The answer is, they're both correct. Just used in different situations.
"Why can't I see?" is a question, asking for the reason the "asker" is not perceiving something.
"Why I can't see" is a statement, not a question. In this case, the person who makes this statement is about to provide a reason for not perceiving something.
Why can't I see?
is a question.
Why I can't see
may be used in a title.
He knows why I can't see
is a statement.
why
Used in questions to ask the reason for or purpose of sth
Used to give or talk about a reason
Used in questions to suggest that it is not necessary to do sth
The sentence
Why can't I see?
is more applicable when you are asking a question [1].
The sentence
Why I can't see?
will be considered grammatically wrong in this case.
However, if you want to talk about the reason behind it (make a statement[2] ), you can use
why I can't see
in a sentence like this:
That's why I can't see.
instead of
That's why can't I see. (grammatically wrong)
But in some countries like Singapore, Hong Kong, etc,
it is alright to ask a question both way.
