approach smb. on the subject

[Irene29]

Hi,

I have come across the following sentence:
It was impossible to approach her on the subject.
Why is “on” used in the sentence? As far as I know the verb “to approach” does not need any preposition. Or is it the set phrase “to approach smb. on the subject?

There are several expressions you could use - about, concerning, regarding, with regard to and so on. The idea of 'approach' here is to tentatively go to someone and ask them about something often seeking their advice/opinion.. Probably 'on' is the most suitable.

Is it possible to say "It was impossible to refer her on the subject"?

The only possible way of saying that would be - to refer to her. That does sound a bit strange and I suggest - to consult her.
