Bahraini travelling around east, having rejected an area in Ireland once (8)
I believe the answer is:
hibernia
'bahraini' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for hibernia that I've seen before include "Latin name for Ireland" , "Old or poetic name for Ireland (8)." , "land once" , "Ancient Ireland" , "Poetic name for Ireland, now archaic" .)
