Daughter abandons laziness to eat son's sauce (9)
I believe the answer is:
insolence
'sauce' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for insolence that I've seen before include "Hubris" , "freshness" , "Lip; cheek" , "Rude disrespect" , "Front" .)
