...the word is invitation not invite!!
You receive an invitation to a wedding. You have therefore been invited to said wedding.
As MN is going to be inundated with wedding-related threads in the next few months (if the last two are anything to go by), I don't think my nerves can take much more confusion over the two words.
Please all, exert yourselves a little and type those four extra letters. It really won't take up that much of your time and will soothe my shredded nerves.
I'd be very, very grateful.
