Extremely old-fashioned servant? (6)
I believe the answer is:
vassal
This could be a double definition.
'extremely old-fashioned' is the first definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'servant?' is the second definition.
(I've seen this in another clue)
Can you help me to learn more?
(Other definitions for vassal that I've seen before include "Medieval land-holder" , "A medieval servant" , "A humble servant as of 9 Down" , "Humble servant or subordinate" , "Feudal retainer" .)
