What does in esse and in posse mean?


New Member
I have come across this phrase a few times

"in esse and in posse"

I think it means something like in reality and in possibility. I am not precisely sure though I would love to have the precise definition. It seems like it is Latin but I looked in a Latin dictionary and couldn't find it. Maybe it wasn't a good Latin dictionary.

    These are legal terms. In esse means in actual existence ( a child who has been born), in posse refers to a fetus in the womb. Thank you, wikipedia.
