Arab rebel soldiers appearing on panel show (5)
I believe the answer is:
iraqi
'arab' is the definition.
(I've seen this before)
'rebel soldiers appearing on panel show' is the wordplay.
'rebel soldiers' becomes 'ira' (I am not sure about this - if you are sure you should believe this answer much more).
'appearing on' means one lot of letters go next to another.
'panel show' becomes 'QI' (BBC panel show).
'ira'+'qi'='IRAQI'
Can you help me to learn more?
(Other definitions for iraqi that I've seen before include "Native of Baghdad, say" , "Citizen of Baghdad, say" , "Language" , "Middle Easterner" , "Probably a Muslim" .)
