Hi everyone, do we get requests from somebody or by somebody? Thanks, Torsten[YSaerTTEW443543]

TOEIC listening, talks: The co-pilot gives flight information to passengers[YSaerTTEW443543]

When “The co-pilot gives flight information to passengers”-ing, I couldn’t determine what you wanted attention directed to that pertained to your query.

Well, the answer is ‘from’ - but others in the forum will say ‘either’ - but why is it either?

‘by’ has the meaning, relevant here, of ‘identifying the agent performing an action’ - so, yes.
‘from’ has the meaning, "indicating the source or provenance of someone or something’. So - yes.

So why do we say:
[color=indigo]“A book by Dickens” and not [color=indigo]“A book from Dickens.”
…yet happily write: “From the desk of…”

This is the second time today I haven’t had a ready answer!
The thinking cap is on for both, the mental juices flowing - my cup overfloweth.
This kind of thing really makes you think about what so readily trips off the tongue…without really understanding the ‘why’.

Later, after a bit of thought:
Is it to do with being a shortened form?
[color=indigo]“A request (coming) from…”
“A request (made) by…”

Bazza,
Are they correct?

  1. If there is a reasonable request from/(X: by) any student, our teacher will accept.
    1a. A personal request from/(X: by) the boss cannot be easily refused.
    1b. This new maths book by/(X: from) Dickens can help to understand this sum.

  2. She is expected to send that request by/(X: from) Friday morning.
    2a. The request by/(X: from) the M.P. to discuss on the floor was refused by the speaker.

Beeesneees,
Could you please help?
Thanks.

If this:
(X:by)
is supposed to indicate that the word in the ellipses is wrong, then you are not wholly correct.

  1. from/by are both possible. “Our teacher will accept” - needs an object noun or pronoun.
    1a. from/by are both possible.
    1b. both possible, though ‘by’ is most likely. “Can help us to understand this sum”.

  2. ‘by’ is likely. ‘From’ is not impossible if it is a repeat request.
    2a both possible, but the second half of the sentence is not grammatical.
