Double dative
In Latin grammar, a double dative is the combination of a dative of reference with a dative of purpose. A common translation is "As a (dative of purpose) with reference to (dative of reference)." This was formerly known as "predicate dative" or "dative of service", with usually the following characteristics of the noun in the dative of purpose: the noun is abstract or semi-abstract; this noun is only in the singular; this noun is used predicatively; there is usually no verb but a form of esse is often understood; this noun is rarely qualified by an adjective unless one like magnus; the noun is rarely qualified by a genitive.
