From the neuter accusative case form of iūgis
iūge (not comparable)
(Late Latin) Synonym of iūgiter
Note the lack of a macron upon the final e, which results from this not being suffixed with the Latin adverbial suffix -ē. Rather, iūge is an example of an adverbial application of the neuter accusative case form of the adjective iūgis, in an example of an adverbial accusative, sometimes called a "frozen accusative" or "petrified accusative" (German "erstarrter Akkusativ"). The adverbs dulce, facile and tantum are other examples of this. The adverbial use of iūge in a late fourth century poem by Prudentius is that first attested.
