Facing losing servant, on vacation once more (5)
I believe the answer is:
again
'once more' is the definition.
(synonyms)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for again that I've seen before include "Ocne more" , "Furthermore" , "repeat order" , "Anew" , "One more time, encore" .)
