HOw would you invite in Arabic a Middle Eastern gentlemen to whom you
have just been introduced to dinner at your house in Riyadh, Saudi
Arabia?2.50

what do u want to say exactly ? 
like "alsalamo alaikom" is the common greeting 
in what accent you want to say it ? in pure arabic ? or the saudi accent ? 
"ohebbo an atasharraf be da'awatikom (da'awatikom for more than 2,
da'awatek for onlt 1, da'awatikoma for 2 ) ela (baiti= my houre)"
this is in pure arabic .. it would differs a bit in saudi accent
in saudi accent u have to hear it to know how to pronounce it .. most
of the letters should be stressed ..
