Pick a released EP, say (6,3)
I believe the answer is:
single out
'pick' is the definition.
(I've seen this before)
'a released ep say' is the wordplay.
I cannot quite understand how this works, but
'released' could be 'out' (eg out of prison) and 'out' is found within the answer.
The remaining letters 'single' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for single out that I've seen before include "Pick" , "record on release" , "Select from group" , "Choose" .)
