Period drama with parts in wrong order creates a gap in education (8)
I believe the answer is:
playtime
'period' is the definition.
(playtime is a kind of period)
'drama with parts in wrong order creates a gap in education' is the wordplay.
I cannot quite see how this works, but
'drama' could be 'play' (synonyms) and 'play' is present in the answer.
The remaining letters 'time' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for playtime that I've seen before include "Break in school day" , "Recreation period" , "Schoolchildren's break" , "Period for pleasure" , "between lessons" .)
