A phrase given by Tolkien as an example of how the subjective case can be used to represent the verb “to be” (SD/429). Since the first noun the subject, the second noun is the predicate and the verb “is” is implied. Depending on context, the sentenced could refer to the past so that the subjective would represent “was” instead. This sentence is contrasted with Ar-Pharazôn kathuphazgânun, where the second noun is inflected in the subjective instead, so that the entire noun phrase would be the subject: “King Ar-Pharazon the Conqueror...”.
