Sprinkle with oil (6)
I believe the answer is:
anoint
'sprinkle with oil' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for anoint that I've seen before include "Administer a sacred oil" , "Choose as successor" , "Administer sacred oils as to the sick" , "Apply consecrated oil to" , "Consecrate with blessed oils" .)
