Elevate, buoy (6)
I believe the answer is:
uplift
I believe this clue is a double definition.
'elevate' is the first definition.
(I've seen this before)
'buoy' is the second definition.
(I've seen this in another clue)
(Other definitions for uplift that I've seen before include "Spiritual elevation" , "Act of raising" , "Increase; moral elevation" , "Elevate, elate" , "Inspire or raise" .)
