Second half of dance perhaps for Joe in LA (5)
I believe the answer is:
mocha
'joe in la' is the definition.
The answer and definition can be both substances as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'second half of dance perhaps' is the wordplay.
'second' becomes 'mo' (both are short periods of time).
'half' suggests halving the letters.
'of' becomes 'o''.
'dance perhaps' becomes 'cha' (I am not sure about this - if you are sure you should believe this answer much more).
'mo' halved is 'm'.
'm'+'o'+'cha'='MOCHA'
'for' is the link.
Can you help me to learn more?
(Other definitions for mocha that I've seen before include "Strong dark coffee" , "Arabian coffee" , "Fine quality coffee" , "Kid" , "Coffee drink" .)
