'Who to?' : prepositions in the end of a sentence

[Tamara]

Hi :)

Not hiding myself behind the Winston Churchill’s back
( http://www.wsu.edu/~brians/errors/churchill.html ),

I'll just bravely quote my favourite British lady, Agatha Christie :)

[Alan]

Hi Tamara,

Just as an aside seeing that you like Agatha Christie, have you ever read any of Dorothy L Sayers?

You asked:

[Tamara]

Hi Alan,

Thank you for the explanation.
(About the links: I’ve read most of your lessons, even though some are at a higher level than I’m still able to comprehend… :( But sometimes I come back and understand a bit more :)).

About 'whom' – OK.

A 'general' question.
Where should I put a preposition in a question that is a complex sentence ending by a 'subordinate' clause - when the preposition is from the main part or is a part of a (transitive) phrasal verb finishing the main part?
In the end of the main clause or in the end of the sentence?

For example:
What do you have to bring a person who put forward such a ridiculous idea so seriously round?
:?

Two 'particular' questions.
Are the sentences correct (from the point of the thread):
When am I to wake you up?
It was about the customs we all grew up with.
?
How would they sound for you if speaking? Fine?

And off-topic questions. :)
About Dorothy L. Sayers – no, I haven't yet read her books. :(

Following your reference, I’ve found several web sites with her biography and brief descriptions of her works.
But some phrases are 'a bit too much' for me :)
Could you help me and explain their meaning, please?

1. Her theology was traditionally Anglican with emphasis on doctrine.

2 She explored by-ways of knowledge

Hi Tamara,

With reference to:

Hi Alan,

Hi Jamie,

This was my – specially created :) – sentence with the phrasal verb bring smb. round.

What (arguments) do you have to bring him round? – would be fine? Or not?

To provide an illustration for my above question, I just replaced <smb.> with the clause
'a person who…'.
– and after that I myself have completely lost the ability to understand it. :)

(Maybe, because I didn’t have German-as-a-second-language at my school time :) ).

Hi Tamara,

Let's rewrite your sentence:

What do you have to do to bring a person round to your point of view,who put forward such a ridiculous idea so seriously?

I see. Then the sentence will be good by moving round next to the verb it belongs to.

What do you have to bring round a person who put forward such a ridiculous idea so seriously?

The issue is not the placement of a preposition, because round is a verb particle here and not a preposition. The reason the sentence was confusing was that it was unclear whether the round was meant to belong to something in the main clause or the adjective clause. Moving it over next to its verb clarifies this. Alan's explanation about the length of the adjective clause is true, but this is because there was a verb intervening between bring and its particle round, so it wasn't clear that the two belonged to each other.
