Nuts cracked in shade (5)
I believe the answer is:
heads
'nuts' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Perhaps you can see a link between them that I don't see?
'cracked in shade' is the wordplay.
'shade' can be anagrammed to 'HEADS'.
However, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for heads that I've seen before include "Goes for" , "Noddles; nuts" , "Ship's latrine; addicts" , "Leaders" , "School principals" .)
