for the term Verum Aeternus (its the name of a song i listen to) I have seen several different translations. I would like to know the exact meaning of these words
Actually such a song title “Verum Aeternus” is absolutely wrong as these two Latin words cannot go together as they should agree in gender, according to Latin grammar, and thus they should sound as "Verum Aeternum" (NOT "Aeternus").
In fact, the noun “Verum” (meaning “truth”) is in the nominative or accusative NEUTER singular, whereas the adjective “Aeternus”(“eternal”) , which is in the nominative MASCULINE, should have been agreed with the neuter noun “Verum” and then it should have been “Aeternum” in the NEUTER singular.
In short, “Verum Aeternus” does not make sense at all in Latin and the correct form should have been VERUM AETERNUM or AETERNUM VERUM, both meaning “Eternal Truth”.
Please note that the noun VERUM (nominative or accusative neuter singular, 2nd declension) means “truth”, while AETERNUM (nominative or accusative neuter singular of the adjective AETERNUS agreed with the noun VERUM) means “eternal”.
