Better articles penned by graduate for boss (3,6)
I believe the answer is:
top banana
'boss' is the definition.
(top banana means a boss or leader)
'better articles penned by graduate' is the wordplay.
'better' becomes 'top' (I've seen this in another clue).
'articles' becomes 'anan' (the indefinite article 'an', twice).
'penned by' is an insertion indicator.
'graduate' becomes 'BA' (someone with a Bachelor of Arts degree).
'anan' going inside 'ba' is 'banana'.
'top'+'banana'='TOP BANANA'
'for' is the link.
(Other definitions for top banana that I've seen before include "head" , "figurehead?" , "first on hand?" , "leader" , "Best of the bunch!" .)
