Prince Charles, who is currently touring the Middle East, is struggling to grasp the Arabic language.
He has been having private tuition for six months to learn it, but revealed today that it "goes in one ear and out the other".
Charles was in Doha, Qatar, at a reception for Qataris who attended UK universities when he told guests: "You all speak such good English."
He has mastered French, speaks German and attempted Welsh, but Prince Charles may have met his match with Arabic.
Learning the language, which is used in the original form of the Koran, could help in his efforts to encourage communication between religions.
After leaving the Qatar-UK Alumni Network he visited the Williams F1 Technology Centre, where he tried out a Range Rover driving simulator.
