Playmaker during sports day showed contempt (7)
I believe the answer is:
pshawed
'showed contempt' is the definition.
The definition suggests a past participle verb which matches the answer.
'playmaker during sports day' is the wordplay.
'playmaker' becomes 'Shaw' (playwright George Bernard Shaw).
'during' is an insertion indicator.
'sports' becomes 'pe' (Physical Education).
'day' becomes 'd' (abbreviation for day).
'shaw' inserted into 'pe' is 'pshawe'.
'pshawe'+'d'='PSHAWED'
Can you help me to learn more?
(Another definition for pshawed that I've seen is " expressed disgust".)
