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


> 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!




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.
