Compelled to redo Verdi composition, finally (6)
I believe the answer is:
driven
'compelled' is the definition.
(to compel is to drive a particular action)
'redo verdi composition finally' is the wordplay.
'redo' is an anagram indicator (letters done in a different way).
'finally' indicates one should take the final letters.
The final letter of 'composition' is 'n'.
'verdi' with letters rearranged gives 'drive'.
'drive'+'n'='DRIVEN'
'to' acts as a link.
(Other definitions for driven that I've seen before include "Propelled like a hard bargain" , "Given a lift" , "(Psychologically) impelled" , "Urged or forced along" , "Highly motivated (informal)" .)
