Put aside aloofness (7)
I believe the answer is:
reserve
I believe this clue is a double definition.
'put aside' is the first definition.
(thesaurus)
'aloofness' is the second definition.

(Other definitions for reserve that I've seen before include "Bank" , "man on bench?" , "Set aside - shyness" , "Keep for future use" , "Reticence" .)
