Bright flower, in short, giving pleasure (4)
I believe the answer is:
glad
This clue might be a double definition.
'bright' is the first definition.
(thesaurus)
'flower in short giving pleasure' is the second definition.
'glad' can be an answer for 'flower' (I've seen this before). I'm unsure of the 'in short giving pleasure' bit.
Can you help me to learn more?
(Other definitions for glad that I've seen before include "These rags are dressy clothes - happy?" , "Informal flower < -girl" , "Feeling pleasure" , "Feeling happy" , "More than willing" .)
