1. James, if you’ll pardon me, you’ve got it all wrong.
2. It was a bit of a cock-up, if you’ll pardon the expression.
When I saw these sentences I wondered if I learned a grammar point wrong! It says in 'if clauses' and 'time clauses' we do not use 'will'
Would you please correct the rule for me? Thanks,
When 'will' expresses the idea of certainty about the future, it is highly unlikely in an if- clause suggesting possibility. You cannot combine certainty and possibility (=lack of certainty).
XI will be surprised if it will rain tomorrow.
When 'will' expresses some idea of willingness, there is no restriction.
If you will come with me, I will take you to Mr Postule's office.
When 'if' has a similar meaning to 'whether', there is no restriction.
Do you know if he will be there tomorrow?
