During a conversation, I heard someone say a French equivalent of it went well. For example, if someone asked you how things had gone on your exam, you might say it went well (if it did indeed go well, of course).
How did the person say it in French?
Ça a bien été.
Ça a can contract to ç’a (sounds like sa), which gives us:
Ç’a bien été.
Because of the liaison, été is actually pronounced n’été here.
If someone tells you this expression doesn’t exist in French, don’t believe it. Ç’a bien été is very frequently used — in Québec, at any rate.
