Physio's work, as during rough games (7)
I believe the answer is:
massage
'physio's work' is the definition.
I can't tell whether this defines the answer.
'as during rough games' is the wordplay.
'during' means one lot of letters goes inside another.
'rough' indicates an anagram (a rough or broken ordering of the letters).
'games' is an anagram of 'msage'.
'as' placed inside 'msage' is 'MASSAGE'.
Can you help me to learn more?
(Other definitions for massage that I've seen before include "Treatment by hand" , "Relaxing treatment" , "See 10" , "Rubbing of muscles" , "therapeutic treatment" .)
