Newly made retreat for high end personal servant (5)
I believe the answer is:
fresh
'newly made' is the definition.
'retreat for high end personal servant' is the wordplay.
'retreat for' says the letters should be written backwards (retreat can mean to go backwards).
'end' indicates one should take the final letters.
'personal servant' becomes 'serf' (a servant in feudal times).
The last letter of 'high' is 'h'.
'h'+'serf'='hserf'
'hserf' in reverse letter order is 'FRESH'.
(Other definitions for fresh that I've seen before include "New; strongish (breeze)" , "Newly-made" , "forward" , "Recently made, produced, or harvested" , "Recently picked" .)
