'girl' is the definition.
(girl's name)

'love spirited' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'spirited' becomes 'live' (I can't justify this - if you can you should believe this answer much more).
'o'+'live'='OLIVE'

Can you help me to learn more?

(Other definitions for olive that I've seen before include "This branch is offered to show peace" , "Stoned fruit" , "Cocktail fruit" , "Female" , "Oily stone fruit" .)

I've seen this clue in The Globe and Mail.
