Whats in the name !!

Sometime back I acompanied my brother-in-law to a doctors clinic. The clinic was named "Ravi Diagnostic Center". On our turn my Brother-in-law was called in by the doctor and I went in with him. The Doctor was a nice man. After He had finished examining my brother-in-law, I casually asked about the unusual name of the clinic "Ravi". He said "you see, my son's name is Ravi and I love him very much, So I named the clinic 'Ravi' as well".
I asked furter "And who named your son Ravi". "Ofcourse me, who else", he replied.
"And what does, Ravi mean", I asked. "The Sun", he replied.

I now wonder how we humans associate meanings with things.
Was the clinic named after The Sun ??
Moreover if you uttered "Ravi" before the Doctor, would he have thought about his clinic, his son or about Ravi-The Sun.
Doctor named his clinic after his son...but who had named his son in first place?? He himself !! So was naming the clinic "Ravi" really concerned with his son or the fact that he liked the name "Ravi" ??
Or was it that meaning of the word "Ravi" changed for the doctor with time. Intially it meant "The Sun"..later its was the name of his son and now its the name of his clinic.......
