Aleppo man in houses of Arabs (5)

I believe the answer is:

omani

I'm a little stuck... Click here to teach me more about this clue!

'of arabs' is the definition.
The definition suggests a singular noun which matches the answer.

'aleppo man in houses' is the wordplay.
'houses' indicates a hidden word (part of the clue houses the answer).
'OMANI' is hidden in the letters of 'aleppo man in'.

Can you help me to learn more?

(Other definitions for omani that I've seen before include "M East person" , "One from Muscat" , "Someone from Muscat" , "Gulf Arab" , "Gulf native" .)

I've seen this clue in The Sun.
