Physiotherapy service required over a long time (7)
I believe the answer is:
massage
'physiotherapy' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe there's a link between them I don't understand?
'service required over a long time' is the wordplay.
'service' becomes 'mass' (mass is a church service).
'required over' is a charade indicator (letters next to each other).
'a long time' becomes 'age' (an age is a period of time).
'mass'+'age'='MASSAGE'
Can you help me to learn more?
(Other definitions for massage that I've seen before include "See 10" , "Relaxing treatment" , "Rubbing of muscles" , "Knead" , "Manipulate to get better results" .)
