Edible leaves for chaps in mess (7)
I believe the answer is:
spinach
'edible leaves' is the definition.
'spinach' can be an answer for 'leaves' (leafy vegetable). I am not sure about the 'edible' bit.
'chaps in mess' is the wordplay.
'mess' is an anagram indicator.
'chaps'+'in'='chapsin'
'chapsin' is an anagram of 'SPINACH'.
'for' is the link.
Can you help me to learn more?
(Other definitions for spinach that I've seen before include "Leaf vegetable" , "Blackboard stand" , "Some greens" , "Popeye the Sailor's vegetable of choice" , "Popeye's strength-giver" .)
