I'm having some trouble with the pronouns quid and quod. It seems to me that Wheelock's uses the former in places where it should use the latter. For example, I translate SA4 in chapter 30 (Nunc scio quid sit amor) as "Now I know what may be love." Shouldn't the Latin word for "what" be a relative pronoun instead of an interrogative?
Thanks to anyone who can help.
