discussion about/on

[Tan Elaine]

Whenever there is a discussion about/on books, somebody will inadvertently mention classics.

Can I use either pronoun?

Thanks.

Can I use either pronoun preposition?.

You can.

[Tan Elaine]

Many thanks, 5jj, for pointing out the mistake. It should be a preposition. I don't why I am often careless. It's part of aging, I suppose.

That's my excuse for all my typos.

I wonder whether you mean inevitably instead of inadvertently.

I rarely accidentally blurt out something about a classic.

Hello Barb

I have checked. The writer must have used the wrong word.

Thanks for pointing out the error.
