Learner attached to sound of poem that's naturally attractive (9)
I believe the answer is:
lodestone
'naturally attractive' is the definition.
I can't judge whether this defines the answer.
'learner attached to sound of poem' is the wordplay.
'learner' becomes 'l' (as in a learner driver with L-plates on their car).
'attached to' is a charade indicator (letters next to each other).
'sound of' becomes 'stone' (I can't justify this - if you can you should believe this answer much more).
'poem' becomes 'ode' (ode is a type of poem).
'stone' put after 'ode' is 'odestone'.
'l'+'odestone'='LODESTONE'
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for lodestone that I've seen before include "Mineral" , "focus of attention" , "attractive person" , "Piece of magnetic iron ore" , "Magnet" .)
