Brisk run expands one's whole self-image? (7)
I believe the answer is:
allegro
'brisk' is the definition.
(I've seen this in another clue)
'run expands one's whole self-image?' is the wordplay.
I cannot quite see how this works, but
'run' could be 'r' (cricket abbreviation) and 'r' is located in the answer.
'whole' could be 'all' (I've seen this in another clue) and 'all' is present in the answer.
'self' could be 'ego' (synonyms) and 'ego' is located in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for allegro that I've seen before include "(In music) briskly" , "(In music) a brisk and lively tempo" , "rather quickly" , "In rapid tempo" , "In a brisk and lively manner" .)
