Royal servants taking over country (5)
I believe the answer is:
yemen
'over country' is the definition.
'yemen' can be an answer for 'country' (I've seen this before). I'm not certain of the 'over' bit.
'royal servants' is the wordplay.
'royal' becomes 'ye' (I can't justify this - if you can you should give a lot more credence to this answer).
'servants' becomes 'men' (man can mean a personal servant).
'ye'+'men'='YEMEN'
'taking' is the link.
Can you help me to learn more?
(Other definitions for yemen that I've seen before include "nation" , "Arab country" , "Aden is found here" , "Arabian country, capital San'a" , "Country between the Red Sea and the Gulf of Aden" .)
