Sponsored youngster did clog dancing outside hotel (8)
I believe the answer is:
godchild
'sponsored youngster' is the definition.
(I've seen this before)
'did clog dancing outside hotel' is the wordplay.
'dancing' indicates anagramming the letters.
'outside' indicates putting letters inside (some letters go outside others).
'hotel' becomes 'h' (phonetic alphabet).
'did'+'clog'='didclog'
'didclog' with letters rearranged gives 'godcild'.
'godcild' going around 'h' is 'GODCHILD'.
(Other definitions for godchild that I've seen before include "Sponsored individual" , "Person to whom one made promises at baptism" , "Sponsored infant" , "Sponsored baptised baby" , "one who's received sponsorship" .)
