I’m a lurker, like youwhere did you pop out of its been a while i think ge is the actual name of the town while harar (harla land) is the name of the province in ancient time. i was told that by a harari historian and this helps with the case https://books.google.ca/books?id=KWQtBAAAQBAJ&pg=PA297&dq=arab+harla&hl=en&sa=X&ved=0ahUKEwi8xM6ni7nSAhUm0oMKHZPECmcQ6AEIPzAH#v=onepage&q=arab harla&f=false
I’m sure gey can he used for other things too though that essentially mean town and place, like quran gey, quran school/learning place
