Royal servant; freeholder (6)
I believe the answer is:
yeoman
This clue is a double definition.
'royal servant' is the first definition.
(I've seen this before)
'freeholder' is the second definition.
(yeoman is a kind of freeholder)
(Other definitions for yeoman that I've seen before include "Officer in the bodyguard of the British monarch" , "Farming freeholder of old" , "farmer with his own land" , "Countryman" , "(Of old) a free person cultivating his own land" .)
