Gain respect (12)
I believe the answer is:
appreciation
This clue is a double definition.
'gain' is the first definition.
(thesaurus)
'respect' is the second definition.
(thesaurus)
(Other definitions for appreciation that I've seen before include "An expression of gratitude" , "It is shown by applause" , "Rise" , "Gratitude; increase in value" , "recognition" .)
