Dancing is a talent or tease (9)
I believe the answer is:
tantalise
'tease' is the definition.
(I've seen this before)
'dancing is a talent' is the wordplay.
'dancing' is an anagram indicator.
'is'+'a'+'talent'='isatalent'
'isatalent' with letters rearranged gives 'TANTALISE'.
'or' acts as a link.
(Other definitions for tantalise that I've seen before include "Tease and entice" , "Tease, torment" , "Tease cruelly" .)
