Recognise, distinguish (4,3)
I believe the answer is:
pick out
I believe this clue is a double definition.
'recognise' is the first definition.
(I know that recognise can be written as pick out)
'distinguish' is the second definition.
(I know that distinguish can be written as pick out)
(Other definitions for pick out that I've seen before include "Play tentatively" , "Distinguished - select" .)
