I’m interested in the translation of “A secret can only be told once”.
I orginally planned to translate it myself but i just don’t have the time required to learn latin (No, i wasn’t planning to learning it just to translate one phrase 
)
Well, there are many ways to express the thought, as usual. I’ll arbitrarily suggest:
“A secret can only be told once”
rebus arcanis semel tantum est locutio
literally “for secrets there is only speech once”. I see this as good Latin, albeit a bit poetic on my part.
For a more exact translation…
res arcana semel tantum dici potest
thank you very much.
the first is more what i was after than an extra translation.
If anyone else has any other suggestions can you post a literal translation with it too?
