I'm really really sorry to butt in, but please let me ask something.
(I personally find this topic interesting because 'organizer' has become part of the Japanese language. As far as the Japanese version is concerned, it doesn't have to be a person. )
1. ABC primary school is organizing the fund-raising fair. 2. What is organizing the fund-raising fair?
Thank you for your kind reply, 5jj.:-D(You saved my life today in another thread. Thank you ever so much.)
And...I quote what I said above. 'Organizer' is a fairly new word, so some people might be using it in the wrong way.
I googled and found many Japanese people use the word in its original sense. I'd like to take back what I wrote in bold.
I'm really sorry if I've caused any misunderstanding.
In English, a school can't organise anything. It is a building. Buildings can't organise or arrange fairs. People organise things, even if they do it on behalf of a school.
