Right, what was that muscle treatment programme? (5)
I believe the answer is:
rehab
'muscle treatment programme?' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'right what was' is the wordplay.
'right' becomes 'r' (abbreviation).
'what' becomes 'eh' (sound used to ask 'what?' or 'pardon?').
'was' becomes 'ab' (I can't explain this - if you can you should believe this answer much more).
'r'+'eh'+'ab'='REHAB'
'that' acts as a link.
Can you help me to learn more?
(Other definitions for rehab that I've seen before include "Restoration to health after, eg, addiction (colloq.)" , "convalescent home?" , "Treatment for addicts (abbrev.)" , "Place to go, in short, to be restored to fitness" , "Treatment for alcohol or drug dependence" .)
