Quartet appearing in sheikdom and sultanate (4)

Ross

I believe the answer is:

oman

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

'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" .)

I've seen this clue in The Guardian.
