Attention paid in learning lessons (3)
I believe the answer is:
ear
'attention' is the definition.
(having someone's ear is having their attention)
'in learning lessons' is the wordplay.
'in' indicates a hidden word.
'EAR' is hidden in the letters of 'learning lessons'.
'paid' is the link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for ear that I've seen before include "Seed container" , "Sensory organ" , "Lughole" , "'Give every man thine ..., but few thy voice'/Hamlet" , "Organ inside heart" .)
