Tout PR i.e. dodgy source of elaborate spin (9)
I believe the answer is:
pirouette
'spin' is the definition.
(pirouette is a kind of spin)
'tout pr i e dodgy source of elaborate' is the wordplay.
'dodgy' indicates an anagram.
'source of' says to take the initial letters.
The first letter of 'elaborate' is 'e'.
'tout'+'pr'+'i'+'e'='toutprie'
'toutprie' with letters rearranged gives 'pirouett'.
'pirouett'+'e'='PIROUETTE'
(Other definitions for pirouette that I've seen before include "Whirl round on one's toes" , "Balletic whirl" , "bit of dancing" , "Rapid spin of the body on the toes in ballet" , "Dancer's twirl" .)
