Excellent selection (6)
I believe the answer is:
choice
This clue is a double definition.
'excellent' is the first definition.
(I've seen this before)
'selection' is the second definition.
(I know that selection can be written as choice)
(Other definitions for choice that I've seen before include "Select" , "Variety" , "Plum" , "Possibility" , "Sophie's ---, William Styron novel" .)
