Celebrated skater upset occasionally (4)
I believe the answer is:
kept
'celebrated' is the definition.
('keep' can be a synonym of 'celebrate')
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for kept that I've seen before include "Saved" , "Retained, held back" , "Retained possession" , "Looked after" , "Maintained, detained" .)
