Graduate leaves yellow fruit for idiots (5)
I believe the answer is:
nanas
'graduate leaves yellow fruit for idiots' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'graduate leaves yellow fruit for idiots' is the wordplay.
'graduate' becomes 'BA' (someone with a Bachelor of Arts degree).
'leaves' indicates named letters should be taken away.
'yellow fruit' becomes 'banana' (I've seen this before).
'for idiots' becomes 's' (I can't justify this - if you can you should believe this answer much more).
'banana' with 'ba' taken away is 'nana'.
'nana'+'s'='NANAS'
Can you help me to learn more?
(Other definitions for nanas that I've seen before include "Old relatives" , "fools" , "which featured on Hey Jude?" .)
