Given medical care at another's expense (7)
I believe the answer is:
treated
'given medical care' is the definition.
(I've seen this before)
'at another's expense' is the wordplay.
I cannot really see how this works, but
'at' is found in the answer.
'another' could be 're' (I've seen this in other clues) and 're' is found within the answer.
The remaining letters 'ted' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for treated that I've seen before include "not asked to pay" , "Given medical care" , "Given medical attention" , "Provided remedies for" , "Applied medication to" .)
