Complete ogre sorted quickly (7)
I believe the answer is:
allegro
'quickly' is the definition.
(musical term)
'complete ogre sorted' is the wordplay.
'complete' becomes 'all' (similar in meaning).
'sorted' indicates anagramming the letters.
'ogre' with letters rearranged gives 'egro'.
'all'+'egro'='ALLEGRO'
(Other definitions for allegro that I've seen before include "In music, fast and lively" , "Scored briskly" , "To be performed in brisk style" , "Instruction to perform in lively fashion" , "Fast (mus.)" .)
