One of the Marx Brothers takes on a barbed dart (7)
I believe the answer is:
harpoon
'a barbed dart' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'one of the marx brothers takes on' is the wordplay.
'one of the marx brothers' becomes 'harpo' (comedian Harpo Marx).
'takes' means one lot of letters go next to another.
'harpo'+'on'='HARPOON'
Can you help me to learn more?
(Other definitions for harpoon that I've seen before include "Barbed whale-spear" , "Whaler's weapon" , "Whale spear" , "Whale-catching missile" , "Barbed whaling spear" .)
