One hates fuss about love (7)
I believe the answer is:
loather
'one hates fuss about' is the definition.
I can't tell whether this definition defines the answer.
'love' is the wordplay.
I cannot really see how this works, but
'love' could be 'o' (In tennis, 'love' means 'zero') and 'o' is found in the answer.
The remaining letters 'lather' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for loather that I've seen before include "I don't like" , "I hate" .)
