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' is an anagram indicator.
'ogre' anagrammed 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.)" .)
