Honour an independent Arab (5)
I believe the answer is:
omani
'arab' is the definition.
(Omani is an example)
'honour an independent' is the wordplay.
'honour' becomes 'om'.
'independent' becomes 'i'.
'om'+'an'+'i'='OMANI'
(Other definitions for omani that I've seen before include "One from Muscat" , "M East person" , "Inhabitant of Middle Eastern sultanate" , "coming from the Middle East" , "Native of one Arabian sultanate" .)
