Good morning every body,
Good morning every one,
Good morning each and every one, I heard "every body" is not good useage. Which one is good usage.
"Everybody" and "everyone" are single words.
I would use "everyone" but my preference for that over "everybody" is probably just personal.
There is no point to saying "each and every one" in this context.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
