Middle Easterner - Gershwin, say - rasied IQ (5)
I believe the answer is:
iraqi
'middle easterner' is the definition.
(someone from Iraq)
'gershwin say rasied iq' is the wordplay.
I cannot quite see how this works, but
'gershwin' could be 'ira' (lyricist Ira Gershwin, brother of George) and 'ira' is located in the answer.
The remaining letters 'qi' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for iraqi that I've seen before include "Inhabitant of Baghdad?" , "Person from Baghdad?" , "Foreign citizen" , "native of troubled land" , "Native of Basra, perhaps" .)
