will and would in if clauses

1. will in if-clauses

Using will to express disapproval of a habit: (e.g. to someone whose bicycle has been stolen)

• If you will* leave your bicycle without locking it up, then you must expect it to be stolen. (* stressed)

Using will to make a formal request:

• If you will sign the documents where I have indicated, we can arrange payment. (Using would instead of will makes it even less direct and therefore even more formal.)

2. would in if-clauses

In polite requests would is possible in if-clauses.

• It would be nice if you would help me in the kitchen. (Are you willing to help me in the kitchen?)
