"Can you give me an idea of what you intend to do?" I tried to think of a phrase including an "idea about" but nothing sounded right. Have you seen it used? It might be used clumsily. But then again, there may be a situation in which it is used but which I can't think of at the moment.

thanks!

Tomas- maybe not. "an entry of" may mean the entry itself (an entry of 10), but "entry about" is describing the subject of the entry ( the woman I met today).

Is it the same case with "an entry of / an entry about" ?

Great! It is helpful.
