Name a half back with rhythmic action (5)
I believe the answer is:
samba
'rhythmic action' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'name a half back' is the wordplay.
'name' becomes 'sam' ().
'a half' means to take half the letters.
'back' halved is 'ba'.
'sam'+'ba'='SAMBA'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for samba that I've seen before include "Latin dance" , "South American dance" , "moves from Brazil" , "it was launched in Brazil" , "Brazilian dance" .)
