A restrained flourish (6)

Ross

I believe the answer is:

abound

'flourish' is the definition.
(I've seen this before)

'a restrained' is the wordplay.
'restrained' becomes 'bound' (binding is a kind of restraining).
'a'+'bound'='ABOUND'

(Other definitions for abound that I've seen before include "Be in ample supply" , "flow" , "Be in plentiful supply" , "Swell" , "Be plentiful - take a jump" .)

I've seen this clue in The Times.
