Mistook/mistaken

[aous02]

we're in a world where the signifier is mistook for the signified

Is it correct to use 'mistook' or it is it more correct to use 'mistaken'?

It has to be "mistaken". It's incorrect to use "mistook".

Thanks.

Yes, mistaken is the correct one you'll use here.

A question from any teacher:

Can we also use Mistook here in this sentence if we change the sentence formation and structure?
Like we're in a world, where the signifier has mistook the signified.
(is has mistook correct????)

No
has or have must be followed by a past participle
so,
"has mistaken" is right.

but I don't think that it could be used in your sentence. It doesn't have the same meaning of the original sentence.
