Are you saying in violence there's no love, just acrimony? (9)
I believe the answer is:
virulence
'acrimony?' is the definition.
(thesaurus)
'are you saying in violence there's no love' is the wordplay.
'are you saying' becomes 'ru' (I can't justify this - if you can you should give a lot more credence to this answer).
'in' means one lot of letters goes inside another.
'there's no' is a deletion indicator.
'love' becomes 'o' (love means zero in tennis).
'violence' with 'o' removed is 'vilence'.
'ru' inserted inside 'vilence' is 'VIRULENCE'.
'just' is the link.
Can you help me to learn more?
(Other definitions for virulence that I've seen before include "Quality of being highly infective" , "Bitterness" .)
