for + noun/pronoun + infinitive
is very common in English. It is used when an infinitive needs its own subject.
- It only takes ten minutes for me to walk to the office.
- It is not necessary for you to wait any longer.
- There were no toys for the children to play with.
- It is now too late for us to begin a new lesson.
- There is nothing more for you to do.
- It is difficult for anyone to control him.
- It isn’t easy for me to let him go.
Some of these sentences can be rewritten with the for-structure as subject.
- For me to walk to the office takes only ten minutes.
- For you to wait any longer isn’t necessary.
- For me to let him go isn’t easy.
In some cases, it is also possible to replace a for-structure with an if-clause.
- It would be risky for you to attempt it.
- It would be risky if you attempted it.
- It wouldn’t be wise for you to boycott the function.
- It wouldn’t be wise if you boycotted the function.
