Bah, Dubai becomes another Middle Eastern emirate (3,5)
I believe the answer is:
abu dhabi
'another middle eastern emirate' is the definition.
The definition and answer can be both locations as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'bah dubai becomes' is the wordplay.
'becomes' indicates an anagram.
'bah'+'dubai'='bahdubai'
'bahdubai' anagrammed gives 'ABU DHABI'.
Can you help me to learn more?
(Other definitions for abu dhabi that I've seen before include "in Middle East" , "Asian capital" , "Persian Gulf emirate" , "Arab state" , "Largest member state of the UAE, and its capital" .)
