Holy one (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
saint
'holy one' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for saint that I've seen before include "Scotland's oldest university" , "Good woman" , "Very virtuous person" , "Holy man" , "paragon!" .)
