Bad at ice-dancing, so renounce title (8)
I believe the answer is:
abdicate
'renounce title' is the definition.
'abdicate' can be an answer for 'renounce' (abdicating is a kind of renouncing). I'm not certain of the 'title' bit.
'bad at ice-dancing' is the wordplay.
'dancing' indicates an anagram.
'bad'+'at'+'ice'='badatice'
'badatice' with letters rearranged gives 'ABDICATE'.
'so' is the link.
Can you help me to learn more?
(Other definitions for abdicate that I've seen before include "Resign from or renounce the throne" , "Renounce position or power" , "stand down" , "Resign from monarchy" , "surrender" .)
