Do return with our bouquet (5)
I believe the answer is:
odour
'bouquet' is the definition.
(I've seen this before)
'do return with our' is the wordplay.
'return' shows that the letters should be reversed in order.
'with' means one lot of letters go next to another.
'do' in reverse letter order is 'od'.
'od'+'our'='ODOUR'
(Other definitions for odour that I've seen before include "Smell; repute" , "reputation" , "Nasty smell" , "A smell, good or bad" , "Smell, scent" .)
