I've been making my way through the book Elementary Japanese Volume 1 and in the chapter on comparatives it introduced this construction:
AとBとでは、どちらの方がXですか。Between A and B, which one is X-er?
AとBとでは、Aの方がBよりXです。 Between A and B, A is X-er than B.
If I understood it correctly then the particles で
and は
are acting as they normally would. Meaning the で
here is the location marker and marks the range of things we are comparing. And the は
particle just marks the whole first part as the topic. However, what I don't understand is the use of the と
particle at the end of the list, right after B
.
I think I have seen this construct without this と
. So what exactly is it's function there?
