Love helping to make speech (7)
I believe the answer is:
oration
'speech' is the definition.
(oration is a kind of speech)
'love helping' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'helping' becomes 'ration' (a ration is a serving or helping).
'o'+'ration'='ORATION'
'to make' acts as a link.
(Other definitions for oration that I've seen before include "lecture" , "A formal or public speech" , "An eloquent speech" , "Type 16 [OF SPEECH]" , "Power of speech" .)
