Love of French poetry (3)
I believe the answer is:
ode
'poetry' is the definition.
(I've seen this before)
'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 "A poem celebrating person or event" , "Lines" , "Poetic composition" , "Verse form" , "- - to a 12 Urn" .)
