Full of sauce during supper time (4)
I believe the answer is:
pert
'full of sauce during supper time' is the definition.
I can't tell whether this definition defines the answer.
'during supper time' is the wordplay.
'during' says the answer is hidden in the clue.
'PERT' can be found hidden inside 'supper time'.
Can you help me to learn more?
(Other definitions for pert that I've seen before include "Forward - saucy" , "Saucy, lively" , "Saucy and impudent" , "Saucy and chipper" , "Jaunty" .)
