Most musical of the Marxes? (5)
I believe the answer is:
harpo
'marxes?' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'most musical of' is the wordplay.
'most musical' becomes 'harp' (I can't explain this - if you can you should give a lot more credence to this answer).
'of' becomes 'o''.
'harp'+'o'='HARPO'
'the' is the link.
Can you help me to learn more?
(Other definitions for harpo that I've seen before include "speechless brother" , "One of the Marx Brothers" , "one from family of comedians" , "The dumb Marx brother" , "brother who never speaks" .)
