An ear for music? (5)
I believe the answer is:
organ
This could be a double definition.
'an ear' is the first definition.
The definition and answer can be both body parts as well as being singular nouns.
Maybe there's an association between them I don't understand?
'music?' is the second definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'for' acts as a link.
Can you help me to learn more?
(Other definitions for organ that I've seen before include "music producer" , "Wind instrument found in the body." , "Instrument with stops" , "Medium of information - most churches have one" , "Brain, for example - instrument" .)
