Presented learner with hammer (5)
I believe the answer is:
gavel
'hammer' is the definition.
(I know that gavel is a type of beetle)
'presented learner' is the wordplay.
'presented' becomes 'gave' ('give' can be a synonym of 'present').
'learner' becomes 'l' (as in a learner driver with L-plates on their car).
'gave'+'l'='GAVEL'
'with' is the link.
(Other definitions for gavel that I've seen before include "equipment for auctioneer" , "Judicial hammer" , "Judge's hammer" , "Small hammer" , "An auctioneer's wooden hammer" .)
