![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
healthy
'free from infirmity or disease' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for healthy that I've seen before include "Fit, undiseased" , "Fit, in sound physical shape" , "Free from infirmity or disease" , "In good shape, not ill" , "Physically sound" .)
