A cuppa for the cleaning lady? (4)
I believe the answer is:
char
'cleaning lady?' is the definition.
(synonyms)
'a cuppa for' is the wordplay.
'a cuppa' becomes 'cha'.
'for' becomes 'r' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'cha'+'r'='CHAR'
'the' acts as a link.
Can you help me to learn more?
(Other definitions for char that I've seen before include "Burn lightly" , "Brown" , "Drink" , "Make black by burning, say toast" , "Sear - fish" .)
