Consequently, the feminine singular subject noun Carthago appears in the nominative case.[3] The verb est[lower-roman 1] functions as a copula—linking the subject noun Carthago to the predicative verbal adjective delenda—and further imports a deontic modality to the clause as a whole.[4] Because delenda is a predicative adjective in relation to the subject noun Carthago, it takes the same number (singular), gender (feminine) and case (nominative) as Carthago.[5]
