One way of handling therapy (9)
I believe the answer is:
treatment
I believe this is a triple definition!
'one way' is the first definition.
(treatment is a kind of way)
'of' is a link.
'handling' is the second definition.
(synonyms)
'therapy' is the third definition.
(I know that therapy can be written as treatment)
(Other definitions for treatment that I've seen before include "See 41 Down" , "Hospital care" , "Discussion" , "patient progress" , "Care provided to improve a situation" .)
