Discussion Groups / English Usage / January 2009

Not really.   These greetings are solely conventional (i.e.
seek no information and convey no information) thus vary
in time and space as the convention varies.   Standard
British reply to thanks is either  "Not at all" or silence (no
answer.)  Standard American reply is "You are welcome"
(not Your Welcome.)   Because this is a convention, you
should conform to local habits of speech (or risk being
misunderstood.)

thx a lot

In England when I was a child the usually response to thanks was
complete silence, and when I first heard "You're welcome" in the US and
Canada I thought it very artificial. However, that was a long time ago,
and nowadays most speakers of British English will issue some sort of
sound, a little grunt, perhaps, or "OK".

In countries where "You're welcome" is standard, I think you need the
"You're", though it doesn't need to be very clearly enunciated.

On the other hand, and looking at your earlier replies, "Thx" is not
much appreciated on this group. If you want to issue thanks you need to
say "Thank you". However, at least you didn't put "sb" in your question.
