cambridge.org: "Will" and "would" can be used in conditional clauses, either with the meaning of ‘being willing to do something’, or to refer to later results:
(1) If Clare will meet us at the airport, it will save us a lot of time.
(2) If you would all stop shouting, I will try and explain the situation!
Cambridge says (1) = (1a):
(1a) If Clare is willing to meet us at the airport, it will save us a lot of time.
I was told here that (2) = (2a):
(2a) If you are all willing to stop shouting, I will try and explain the situation!
From these examples I infer that in the meaning of ‘being willing to do something’:
will = would = am/are/is willing to
Therefore, I can replace "will" and "would" with each other without changing the meaning:
(3) If Clare would meet us at the airport, it will save us a lot of time.
(4) If you will all stop shouting, I will try and explain the situation!
That is:
(1) = (3)
(2) = (4)
If I'm not right, tell me please:
Why does my logic not work?
What is the difference between (1) and (3)?
What is the difference between (2) and (4)?
