Dances about, but will get up (6)
I believe the answer is:
ascend
'get up' is the definition.
(I've seen this in another clue)
'dances about but' is the wordplay.
'dances' can be anagrammed to 'ASCEND'.
However, I'm not sure how this is indicated.
'will' is the link.
Can you help me to learn more?
(Other definitions for ascend that I've seen before include "Scale" , "Make the top" , "shift to a higher plane" , "Soar" , "Travel upwards" .)
