Love of French poem (3)
I believe the answer is:
ode
'poem' is the definition.
(ode is a kind of poem)
'love of french' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'of french' becomes 'de' ('of' in French).
'o'+'de'='ODE'
(Other definitions for ode that I've seen before include "Lyric poem" , "Sung poem" , "A poem celebrating person or event" , "(Railway)system" , "Poem expressing noble feelings" .)
