I‘m learning Adjektivdeklination from a workbook, and I came to this question where I believe the answer of the book is false.
Heute ist einer der heißest_ Tage des ganzen Jahres.
The answer written in the book is:
heißeste
, whereas
Tage
is plural and, thus, it should be, I think:
heißesten
Can anyone please assist me in that? Thanks :)
