Lack of guile and love found in a dog (7)
I believe the answer is:
candour
'lack of guile' is the definition.
The definition and answer can be both human attributes as well as being singular nouns.
Maybe there's a link between them I don't understand?
'and love found in a dog' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'found in' indicates putting letters inside.
'a dog' becomes 'cur' (a cur is an aggressive or scruffy dog).
'and'+'o'='ando'
'ando' put into 'cur' is 'CANDOUR'.
Can you help me to learn more?
(Other definitions for candour that I've seen before include "open)" , "Frankness, openness" , "'Frankness, honesty (7)'" , "Forthrightness" , "sincerity" .)
