Dance nut beginning to dance a dance without an introduction (8)
I believe the answer is:
fandango
'an introduction' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'dance nut beginning to dance a dance without' is the wordplay.
'beginning to' indicates taking the first letters.
'dance' is an anagram indicator.
'dance' becomes 'fango' (I can't justify this - if you can you should give a lot more credence to this answer).
'without' indicates putting letters inside.
The initial letters of 'dance nut' is 'dn'.
'dn' is an anagram of 'nd'.
'nd'+'a'='nda'
'nda' going inside 'fango' is 'FANDANGO'.
Can you help me to learn more?
(Other definitions for fandango that I've seen before include "Spanish dance -- a dong fan (anag)" , "Old Spanish dance in triple time" , "Dance performed with castanets" , "Old Spanish dance, with castanets" , "Spanish courtship dance in triple time" .)
