Excellent physical education: hurting all over? (6)
I believe the answer is:
peachy
'excellent' is the definition.
(I've seen this before)
'physical education hurting all over?' is the wordplay.
'physical education' becomes 'pe'.
'hurting all over?' becomes 'achy' (I've seen this in another clue).
'pe'+'achy'='PEACHY'
(Other definitions for peachy that I've seen before include "excellent!" , "Delicious" .)
