Every once in awhile in my drawings I like to put phrases in other languages on my personal work and I want to name my next piece Secrets Unknown and I would like to put it Latin. So my question is what is the Latin translation for secrets unknown? Thank you so much for any help given, I appreciate it.
“Arcana incognita” is the translation you are looking for.
Please note that “Arcana” (nominative neuter plural of the noun “arcanum”, 2nd.declension) corresponds to “secrets”, while “incognita” (nominative neuter plural of the adjective “incognitus” agreed with “arcana”) means “unknown”.
