I'm looking for information on Yemen, please. 
 Sure, I'm happy to provide information. Yemen is a nation in the Middle East. It borders Saudi Arabia and Oman on the north and east. It lies at the coordinates between latitudes 12 and 19 degrees N and longitudes 42 and 55 degrees E. It is 527,970 km2 in size. 
 Thank you. What can you tell me about the etymology? 
 As for its etymology, I can tell you that ancient Yemen was referred to as South Arabia and Latin and Greek writers used the name "India" to refer to it. 
 Thanks. What else can you tell me about that? 
 I can tell you that the origin of using the term "India" was because of the fact that the Persians called the Abyssinians they came into contact with in South Arabia by the same name as the dark skinned people who lived next to them which was the Indians. 
 Interesting! What else can you tell me about the etymology? 
 I do not have any more information but I can tell you that the Federation of South Arabia was created by the British to counter Arab nationalism by giving more freedom to the rulers of the nations. 
 That's great, thanks. What can you tell me about the geography? 
 I'm glad you asked! In the Tihamah evaporation is so great that streams from the highlands never reach the sea, but contribute to extensive groundwater reserves. 
 Wow. Can you elaborate? 
 Yes, perennial streams occur in the highlands and the Tihamah ends abruptly at the escarpment of the western highlands. 
 Great info, thanks! 
 You're welcome! Have a great evening!
