Protective spirit? (8,5)
I believe the answer is:
guardian angel
'protective spirit?' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for guardian angel that I've seen before include "Protector (ours?) - city vigilante" , "spirit of helpfulness" , "One watching out for another" , "Friendly spirit" , "Protective spirit" .)
