What can you help me learn about Wales? 
 Hi. Well, Wales is a country of Great Britain. It's one of the six Celtic nations. 
 I didn't know there were six of them. What can you tell me about the etymology? 
 Historically in Britain, the words were not restricted to modern Wales or to the Welsh but were used to refer to anything that the Anglo-Saxons associated with the Britons , including other non-Germanic territories in Britain (e.g. Cornwall) and places in Anglo-Saxon territory associated with Britons (e.g. Walworth in County Durham and Walton in West Yorkshire). 
 Hmmm, great to know. I'd like more etymology information like that if you have any to share. 
 The English words "Wales" derive from the same Germanic root which was itself derived from the name of the Gaulish people known to the Romans as Volcae and came to refer indiscriminately to all non-Germanic peoples. 
 That's very helpful. I'm also interested in learning about transport related to Wales. What can you tell me about that? 
 Wales' busiest railway station is the Cardiff Central. It has over four times as much passenger traffic as any other station in Wales. 
 Sounds busy. What else do you have for me on the topic of transport? 
 A470 is the main north-south Wales link, which runs from Cardiff to Llandudno. 
 Is there anything more you think I should know about transportation in Wales today? 
 The A55 expressway has a similar role along the north Wales coast, connecting Holyhead and Bangor with Wrexham and Flintshire. 
 That's all very helpful. Thanks for helping me out. 
 My pleasure. Have a good evening.
