Backward throw (3)
I believe the answer is:
shy
This clue is a double definition.
'backward' is the first definition.
(thesaurus)
'throw' is the second definition.
(I have seen 'Quick throw ' mean 'shy' so perhaps 'throw' could also mean 'shy')
(Other definitions for shy that I've seen before include "Throw in bashful way" , "Timid (around people)" , "Nervous or timid in company" , "Reserved" , "Chary" .)
