Turned to give snack to journalist (6)
I believe the answer is:
rolled
'turned' is the definition.
(rolling is a kind of turning)
'snack to journalist' is the wordplay.
I cannot quite see how this works, but
'journalist' could be 'ed' (short for editor) and 'ed' is located in the answer.
The remaining letters 'roll' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'to give' acts as a link.
Can you help me to learn more?
(Other definitions for rolled that I've seen before include "Rotated" , "Moved along on wheels" , "Furled" .)
