Grammar Question

[khaleesi]

if you ask a question in the middle of a sentence, should you use a question mark?
i.e should it be
Do you know what time you will be here, as i would like to go the shops before you come
or
Do you know what time you will be here? As i would like to go to the shops before you come

[jno]

tricky, but I'd split it into two sentences, as in your second suggestion.

[Cloverjo]

I think the question mark should be at the end.

At the end

[EDDIE51]

The second is correct but also use a capital 'I' to indicate the first person.
Probably better to say 'before you arrive' rather than' before you come' as well!

[Buenchico]

If you insist upon using the conjunction 'as', "Do you know what time you will be here, as I would like to go the shops before you come?" is possibly acceptable.

Your second option can't be correct, as you'd be starting the second sentence with a conjunction

My own preference would be to ditch the conjunction:
"Do you know what time you will be here? I would like to go to the shops before you come"

Possibly better still, since the second sentence serves to explain the first one (and the presence of the question mark rules out the use of a semi-colon), parentheses could be used:
"Do you know what time you will be here? (I would like to go to the shops before you come)"

I would split into two sentences and punctuate accordingly

there are various levels of English which are now recognised
with Clarity being the only criterion
Literary - polite formal - polite office - vernacular office and language you use at a take away

and one can even be tested in it
Fatima posted alot on questions i recognised from an accouns course I did last year

it is technically called an embedded question
- i use embedding a lot but it does make the prose not flow ( as you can see ) very smoothly

so I googled how do you punctuate an embedded question
and hey there are even sites ( golly gosh! ) [ would you believe it?] on it

[Peter Pedant]

for clarity I think you should split into two sentences

start a sentence with a conjunction as often as you like.

lol, oh eddie I say that all the time, I didn't realize how rude it was until now.
I was told not to use short sentences though... that's way I posted the question
I think chris is onto a winner with his brackets idea

[khaleesi]

thank you so much for that link and explanation peter, that's such a good idea too

[ichkeria]

If you want my opinion there is nothing wrong with your first sentence, minus question mark.

[Jackdaw33]

I agree with jno. There is nothing wrong with starting a sentence with a conjunction or ending one with a preposition, no matter what others may say.
