Taxi order received by phone for nightclub (7)
I believe the answer is:
cabaret
'for nightclub' is the definition.
(synonyms)
'taxi order received by' is the wordplay.
'taxi' becomes 'cab' (synonyms).
'order' becomes 're' (I am not sure about this - if you are sure you should believe this answer much more).
'received' means one lot of letters goes inside another.
'by' becomes 'at'.
're' going into 'at' is 'aret'.
'cab'+'aret'='CABARET'
'phone' acts as a link.
This may not be right. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for cabaret that I've seen before include "Stage show" , "Liza Minnelli's entertainment?" , "Bob Fosse musical with Liza Minnelli" , "goes on in nightclub?" , "Bear cat (anag.)" .)
