Love of the French poetry (4)
I believe the answer is:
odes
'poetry' is the definition.
(ode is a type of poem)
'love of the french' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'of the french' becomes 'des' ('of the' in French).
'o'+'des'='ODES'
(Other definitions for odes that I've seen before include "Verses" , "Works by Pindar" , "Lyric poems" , "Poems in praise" , "Lines" .)
