Latine

In hac sententia Orberg scribit: “Tu non modo foedissime, sed etiam pravissime scribis, Marce! Nescis Latine scribere!”

Num vocabulum ‘Latine’ est adverbium?

Ita: ‘latin-ly’

“Latīnē” is indeed an adverb meaning “in Latin”. Other languages get the same treatment, e.g. “Anglicē” for “in English”.

Thanks guys.
