Pretend there are no problems with father exercising dog? (5,4)
I believe the answer is:
paper over
'pretend there are no problems' is the definition.
I can't tell whether this defines the answer.
'with father exercising dog?' is the wordplay.
'with' is a charade indicator (letters next to each other).
'father' becomes 'pa' (pa can mean dad or father).
'exercising' becomes 'pe' (abbreviation for Physical Education).
'dog?' becomes 'rover' (Rover is a common name for a pet dog).
'pa' next to 'pe' is 'pape'.
'pape'+'rover'='PAPER OVER'
Can you help me to learn more?
(Other definitions for paper over that I've seen before include "Pretend there's no real problem with" , "Try to hide fault" , "Disguise bad news" , "Conceal" .)
