What croupier might say is perfect? (5)
I believe the answer is:
ideal
'is perfect?' is the definition.
(similar in meaning)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for ideal that I've seen before include "existing only in imagination" , "A deli (anag.)" , "Model of excellance" , "Just the ticket" , "Most suitable" .)
