Very happy, elated (6)
I believe the answer is:
joyful
This clue is a double definition.
'very happy' is the first definition.
(I've seen this before)
'elated' is the second definition.
(I know that elated can be written as joyful)
(Other definitions for joyful that I've seen before include "Happy" , "In state of extreme gladness" , "Full of glee" , "Feeling great happiness" , "Feeling rapture or delight" .)
