RTUR Hungarian from 1950 My grandparents, Matyi, brought it to the US from Hungary. RTUR was their Hungarian pronunciation of Artur around 1950. US immigrants. Heavy accentuation on the "AR" with hard "t".
It's a current name in France too (Broceliande, Merlin and the Knights of the Round Table are very famous in Brittany). The French pronunciation is AHR-TUYR. [noted -ed]
The correct pronunciation is: /'ɑr.tyr/ [noted -ed]
Also compare the short form Tuur in the main database.
You had the correct pronunciation in the past; I don't understand why you suddenly changed it to the current one in December 2022.
