Delight, happiness (4)
I believe the answer is:
glee
I believe this is a double definition.
'delight' is the first definition.
(glee can mean great joy)
'happiness' is the second definition.
(I know that glee is a type of happiness)
(Other definitions for glee that I've seen before include "Happiness" , "Part-song for male voices - delight" , "Sort of club" , "Unholy delight" , "Impish enjoyment" .)
