Knocker provided by learner (5)
I believe the answer is:
gavel
'knocker' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'provided by learner' is the wordplay.
'provided' becomes 'gave' (giving is a kind of providing).
'by' is a charade indicator (letters next to each other).
'learner' becomes 'l' (as in a learner driver with L-plates on their car).
'gave'+'l'='GAVEL'
Can you help me to learn more?
(Other definitions for gavel that I've seen before include "Judge's hammer" , "equipment for auctioneer" , "Small mallet" , "Ceremonial mallet" , "Mason's hammer" .)
