Suppose I want to be particularly emphatic about a noun: "the Fates themselves must have turned against me!" In Latin, I'd use some form of ipse; in Greek, my first instinct is αὐτός.
But I've also heard that αὐτός means "same" instead of being an intensifier when there's a definite article involved. That's not my goal here.
So if I also need to have a definite article (e.g. because the noun always takes one, like αἱ Μοῖραι "the Fates"), how would I make the noun more emphatic?
