Send to cloud nine (5)
I believe the answer is:
elate
'send to cloud nine' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for elate that I've seen before include "transport?" , "Delight" , "Fill with joy" , "Lift (the spirits)" , "Doctor suitor to Anne Page (MWOW)" .)
