What does Exante mean in Greek?

Hello.

I believe that it's Latin rather than Greek.  It means "from before"
or "beforehand."

'Definition of Ex Ante / Ex-Ante?
...
Definition: Ex ante is latin for "beforehand". In models where there
is uncertainty that is resolved during the course of events, the ex
antes values (e.g. of expected gain) are those that are calculated in
advance of the resolution of uncertainty.'
