Pulling back or turning in (10)
I believe the answer is:
retirement
This could be a double definition.
'pulling back' is the first definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'turning in' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'or' acts as a link.
Can you help me to learn more?
(Other definitions for retirement that I've seen before include "Going to bed? - I met renter (anag)" , "period as emeritus?" , "Process of withdrawing" , "Time without any work being done" , "Seclusion; end of work" .)
