The meaning and nuance behind the phrase "話は通してある"

Question

話は通してある

This is a phrase I've come across a few times recently in manga.

For example:

「ユキにも話は通してある」

I'm not familiar with it so I'm not quite sure of it's correct meaning and usage, looking online I've only managed to find a meaning for the phrase: "話を通して" - with the を particle instead of the は - which means to "get it explained to…/run it by…" with the nuance of getting consent from somebody.

How does 話は通してある differ? Does it have a similar or even the same meaning as 話を通して? Or if it 話は通してある has a different meaning completely, will someone kindly explain?

Many thanks!

Answer 1

It has roughly the same meaning as 話を通してある. The key here is that you can replace を with は when the object is focused or contrasted. It's a general grammatical rule.

• Why can は and を sometimes be used interchangeably?
• "は + verb" instead of "を + verb"?
