Green fruit can turn along the way (7)
'green' is the definition.
(spinach is a kind of green)
'fruit can turn along the way' is the wordplay.
I cannot quite see how this works, but
an anagram of 'can' is 'nac' which is located in the answer.
'way' could be 's' (Compass direction - South) and 's' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for spinach that I've seen before include "Vegetable, source of iron", "Some greens", "something to eat", "Vegetable plant", "Vegetable leaves".)
