Quartet appearing in sheikdom and sultanate (4)
I believe the answer is:
oman
'sultanate' is the definition.
(I've seen this before)
'quartet appearing in sheikdom and' is the wordplay.
'OMAN' is hidden in amongst the letters.
However, I am not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for oman that I've seen before include "Sultanate on the south-east coast of the Arabian Peninsula" , "monarchy" , "Arabian peninsula country" , "Middle Eastern country" , "Sultanate in southwest Asia" .)
