Second employer (8)
I believe the answer is:
duellist
This clue might be a double definition.
'second' is the first definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'employer' is the second definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see an association between them that I can't see?
Can you help me to learn more?
(Other definitions for duellist that I've seen before include "Fighter" , "Person engaged in single combat" , "he calls one out" , "Combatant in deadly fight between two people" , "one fighting on a point of honour" .)
