Nessie, you'll help us a lot if you give us an example of what originally caused the confusion.

I don't know, I just think that only "blessings" is used commonly, but when I checked it on the BNC, I found that both are used, so I'm rather confused...

Well, if you checked it in the BNC, then you must have some sentence examples that surprise you.
