I just put together this sentence and I am not sure it is a 100% correct, so I would like you guys to take a look at it, it is kind of complicated:
"Yeah well do you have any idea what specifically, it is that I should ask to get changed then?"
Also I would like to ask if there is any difference between concerning and regarding, to me it seems as though they can be used interchangeably. Is that so?
In other words, of course there's a difference. One is the present participle of 'concern' and the other of 'regard'. These are completely different words with fundamentally different meanings, connotations and usages.
And this will be the answer for almost questions about two different words without context being "interchangeable".
PS: Oops, I notice bhai has answered you. I'd suggest that if two words "can't also be used interchangeably", then they aren't interchangeable.
