Drink to a good man? (5)
I believe the answer is:
toast
'drink' is the definition.
(toast is a kind of drink)
'to a good man?' is the wordplay.
'good man?' becomes 'st'.
'to'+'a'+'st'='TOAST'
(Other definitions for toast that I've seen before include "Perhaps all the best" , "Health-giving" , "Breakfast slice" , "cooked 13 [BREAD]" , "Cheers" .)
