Ancient citizen it's hard work to be like (6)
I believe the answer is:
trojan
'ancient citizen' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for trojan that I've seen before include "Hard-working, trustworthy person (but, of a horse, untrustworthy!)" , "Paris, for example - harmful computer program" , "one typically hard-working" , "This horse was a wooden decoy" , "Hard grafter (from an ancient city?)" .)
