I'm trying to figure out the grammatical rule in using the ending EN in "irgendeinen" in the sentence:
Hast du irgendeinen dieser Romane gelesen?
Since "the novels" is plural in die Romane, and it's using the genitive in asking whether or not you've read any of these books, I thought the "any" would have been accusative?
The ending with en is usually seen in either dative pleural or masculine accusative, both of which don't seem to fit in the above construction.
I thought the any would then have been irgendeine dieser Romane?
