Foreign order to air question one (5)
I believe the answer is:
iraqi
'foreign' is the definition.
Although both the answer and definition are adjectives, I don't see how one could define the other.
'order to air question one' is the wordplay.
'order to' is an anagram indicator (a different order to the letters).
'question' becomes 'q'.
'one' becomes 'i' (Roman numeral).
'air' is an anagram of 'ira'.
'ira'+'q'+'i'='IRAQI'
Can you help me to learn more?
(Other definitions for iraqi that I've seen before include "Native of Baghdad, perhaps" , "Arab national" , "foreigner" , "Resident of Baghdad, say" , "around Baghdad?" .)
