Dancing Elvis with this? (6)
I believe the answer is:
swivel
'this?' is the definition.
The definition suggests a singular noun which matches the answer.
'dancing elvis with' is the wordplay.
'dancing' indicates an anagram.
'with' becomes 'w' (abbreviation).
'elvis'+'w'='elvisw'
'elvisw' with letters rearranged gives 'SWIVEL'.
Can you help me to learn more?
(Other definitions for swivel that I've seen before include "Turn on a chair, say" , "Kind of chair with seat that turns horizontally" , "Rotating coupling" , "Turn on the spot" , "Spin on the spot" .)
