To my (limited) knowledge, one has to put the nominalizer `の/ん` between a verb
and a copula. However, when I was learning the usage of である, the written,
literary copula, I read that `であろう` can follow a verb directly. That was when
I realized that `だろう/でしょう` works in the same fashion.

I understand that の/ん is optional context-wise in this case, but how come the
so-called volitional form does not need to have the preceding verb
nominalized?

question
copula modality
Why is verb (plain, dictionary form) + だろう/でしょう/であろう grammatical?
