Aleppo man in houses of some Arabs (5)
I believe the answer is:
omani
'some arabs' is the definition.
(the people of Oman)
'aleppo man in houses' is the wordplay.
'houses' indicates a hidden word (part of the clue houses the answer).
'OMANI' can be found hidden inside 'aleppo man in'.
'of' acts as a link.
(Other definitions for omani that I've seen before include "coming from the Middle East" , "Native of one Arabian sultanate" , "one from the Middle East" , "Middle East national" , "M East person" .)
