Speak of one's love for speed? (5)
I believe the answer is:
orate
'speak of one's' is the definition.
'orate' can be an answer for 'speak' (orating is a kind of speaking). I am unsure of the 'of one's' bit.
'love for speed?' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'for' means one lot of letters go next to another.
'speed?' becomes 'rate' (both can mean pace).
'o'+'rate'='ORATE'
Can you help me to learn more?
(Other definitions for orate that I've seen before include "Speak like Cicero?" , "Deliver a speech" , "Make a formal speech" , "make speeches" , "Speak in florid style" .)
