Rocking teen vamp is sort of artist (8)
I believe the answer is:
pavement
'sort of artist' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'rocking teen vamp' is the wordplay.
'rocking' indicates an anagram.
'teen'+'vamp'='teenvamp'
'teenvamp' with letters rearranged gives 'PAVEMENT'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for pavement that I've seen before include "Raised footway by road" , "route for walkers" , "Way" , "Pedestrians' path" , "Roadside walkway" .)
