Exactly how much of a snob are you?
Will you happily say Good morning? Or would that be too posh?
Will you say Hi, or Hey: or would that be too modern?
Are you fussy to the point that you don't even approve of Hello? (It is just about possible: the word, used as a greeting, is less than a hundred and fifty years old, and was coined by an engineer* rather than a classics scholar).
Will you say Good day? or is that too ridiculously formal (unless, of course, you're Australian)?
And how about wotcher? That manages to be out-of-date, slang, and never used in middle-class society...
Are you a snob?
Go on, then, prove it: greet the next person you see with wotcher.
I'll let off the Americans amongst you saying the next word in the traditional greeting:
Word To Use Today: wotcher. This is Cockney (that is, east London slang) for What cheer? It was coined in the 1800s.
Actually, I do wish What cheer would come back as a greeting: it might stop everyone grumbling the whole time.
The word cheer, in the sense of a welcoming face, comes from the Greek kara, which means head.
*Thomas Edison. It was originally an exclamation of surprise at the workings (or lack of them) of his newly invented telephone.
