Run for office (6)
I believe the answer is:
career
This clue could be a double definition.
'run' is the first definition.
(thesaurus)
'office' is the second definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe there's a link between them I don't understand?
'for' is the link.
Can you help me to learn more?
(Other definitions for career that I've seen before include "someone in profession" , "series of jobs" , "Hurtle" , "Lifetime's occupation" , "Rush madly" .)
