Listen and learn (4)
I believe the answer is:
hear
I believe this is a double definition.
'listen' is the first definition.
(I've seen this before)
'learn' is the second definition.
(I've seen this before)
'and' acts as a link.
(Other definitions for hear that I've seen before include "Discover aurally" , "Perceive sound" , "Pick up, aurally" , "Listen to" , "Pay attention" .)
