Got an alternative routine (5)
I believe the answer is:
tango
'routine' 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 don't see?
'got an alternative' is the wordplay.
'alternative' indicates an anagram (an alternative ordering of the letters).
'got'+'an'='gotan'
'gotan' with letters rearranged gives 'TANGO'.
Can you help me to learn more?
(Other definitions for tango that I've seen before include "South American dance (for two?)" , "reputedly takes two" , "Colourful dance from Argentina" , "Dramatic ballroom dance from Argentina" , "Latin American dance takes two to do it" .)
