Rise when clubs finish (6)
I believe the answer is:
ascend
'rise' is the definition.
(I know that rise can be written as ascend)
'when clubs finish' is the wordplay.
'when' becomes 'as' (eg 'when I walked' means 'as I walked').
'clubs' becomes 'c' (abbreviation in card games).
'finish' becomes 'end' (synonyms).
'as'+'c'+'end'='ASCEND'
(Other definitions for ascend that I've seen before include "shift to a higher plane" , "Climb, go up (6)" , "Come up" , "Travel upwards" , "Take off" .)
