Accident-prone dancer (7)
I believe the answer is:
tripper
'dancer' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'accident-prone' is the wordplay.
'accident' becomes 'trip' (trip is a kind of accident).
'prone' becomes 'per' (I can't explain this - if you can you should give a lot more credence to this answer).
'trip'+'per'='TRIPPER'
Can you help me to learn more?
(Other definitions for tripper that I've seen before include "Someone on an excursion" , "One who makes an excursion" , "One hoping to enjoy journey" , "Someone out for day" , "at risk of sustaining injury?" .)
