Dancer pulls him for one frenetic night when the magic happens (5)
I believe the answer is:
santa
'dancer pulls him' is the definition.
The definition suggests a singular noun which matches the answer.
'one frenetic night when the magic happens' is the wordplay.
I cannot really see how this works, but
'one' could be 'an' (an apple is one apple) and 'an' is located in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
The remaining letters 'sa' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
(Other definitions for santa that I've seen before include "generous visitor" , "St Nicholas" , "distributer of goodies" , "bringer of gifts" , "Present bringer" .)
