"your explanation appears to be a longer version of mine"
- a conventional greeting used mostly after being introduced to someone
- although it is a question, it requires no reply
- originally, in the 1600s, this expression was an inquiry after a person's health or standing, how do you do meaning "how do you fare?"
So, unless you happen to live in the 1600s, "my" explanation is more or less the exact opposite of your interpretation of the phrase - unless I'm being daft, which I have been known to be once in a while. ;-)
"hope that someone can provide a source of the explanation of"
I'm not sure why you feel that the comments of several native speakers of the English language don't suffice, but here you go:
"How do you do? is very formal and is not used very much, especially by younger people, these days. It may be used on first meeting and accompanied by a formal handshake when both partners issue the same greeting. The reply to How do you do? is How do you do? Then it would be a matter of getting straight down to the business in hand, e.g. ‘I see that your company has been performing very well in South East Asia...'
The more usual exchange between two people meeting with a handshake on a fairly formal basis for the first time would be: Pleased to meet you. Or: Nice to meet you."http://www.bbc.co.uk/worldservice/learningeng...
The usual formal greeting is a 'How do you do?' and a firm handshake, but with a lighter touch between men and women.
‘How do you do?’ is a greeting not a question and the correct response is to repeat ‘How do you do?' You say this when shaking hands with someone.
How do you do? – How do you do?
'How are you?' is a question and the most common and polite response is "I am fine thank you and you?""http://www.woodlands-junior.kent.sch.uk/custo...
