A high spirited one, this girl? (6)
I believe the answer is:
angela
'this girl?' is the definition.
'a high spirited one' is the wordplay.
'a high spirited' becomes 'angel' (I can't explain this - if you can you should give a lot more credence to this answer).
'one' becomes 'a'.
'angel'+'a'='ANGELA'
Can you help me to learn more?
(Other definitions for angela that I've seen before include "- Gheorghiu, Romanian soprano" , "woman" , "Girl's name" , "-- Merkel, German Chancellor" , ". . . Lansbury (actress)" .)
