408. We have learned that the word denoting the owner or possessor of something is in the genitive, as, equus Galbae\, _Galba’s horse._ If, now, we wish to express the idea _the horse is Galba’s_, Galba remains the possessor, and hence in the genitive as before, but now stands in the predicate, as, equus est Galbae\.  Hence this is called the predicate genitive.

409. RULE.  Predicate Genitive. The possessive genitive often stands in the predicate, especially after the forms of /sum\, and is then called the predicate genitive.
