Hi teachers,

Could you please tell me whether there is a difference between inform on something, inform
of something and inform about something?

I was told to use of when the object is specified, about when it's not. Is that so?

Then, are these two sentences fine?

a) The frequency expression informs of the frequency with which she has studied Spanish in the past.

b) She should be inform about any changes.

Thanks in advance

The choice of the preposition seems to be more a matter of personal preference and fashion than anything else. On is particularly fashionable at the moment especially in American English.

Hi Cool Breeze,
