In dubio pro reo, carpe diem, in vino veritas, or errare humanum est: In our everyday language, we often use Latin expressions and phrases, sometimes without knowing their meanings or origins. This ends now, as "Nomen est Omen" includes the most well-known Latin quotes and phrases, explains their origins, identifies their authors, and clarifies their current usage. It includes a German translation that conveys the intended meaning, as well as two clear indexes—one sorted by German translation and the other by authors.
