Isn’t the grammar description missing the case where せい is followed by だ/です? Apparently, the particle で is not allowed in that case, whereas the grammar summary indicate that it is required there:

✗ ~せいででしょう。
○~せいでしょう。

Hey :slight_smile:

It is not allowed here, because で in せいで is てform of a noun/なadjective, and the てform is used to connect parts of the sentence (clauses). When せい is used at the end of the sentence (so-called predicate position), there is no other part that will be joined so てform is not needed and as with any other noun/なadjective だ・です・and so on follow.

I will fix the structure section so it will be more clear :slight_smile:

Cheers,
I hope it helps!
