Dancer likely to be up on points? (9)
I believe the answer is:
ballerina
'dancer' is the definition.
(ballerina is a kind of dancer)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for ballerina that I've seen before include "She's a classical dancer" , "girl on point duty" , "Dancers" , "lass good at splits?" , "girl from the Kirov?" .)
