Speak, and put a value on love (5)
I believe the answer is:
orate
'speak' is the definition.
(orating is a kind of speaking)
'value on love' is the wordplay.
'value' becomes 'rate' ('rate' can be a synonym of 'value').
'on' means one lot of letters go next to another.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'rate' put after 'o' is 'ORATE'.
'and put a' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for orate that I've seen before include "Lecture" , "Speak in florid style" , "Speechify" , "Speak pompously and at length" , "Make a flowery speech" .)
