Samples good man rudely eats outside (6)
I believe the answer is:
tastes
'samples' is the definition.
(I know this)
'good man rudely eats outside' is the wordplay.
'good man' becomes 'st' (abbreviation for saint).
'rudely' indicates anagramming the letters.
'outside' indicates putting letters inside.
'eats' anagrammed gives 'taes'.
'st' inserted inside 'taes' is 'TASTES'.
(Other definitions for tastes that I've seen before include "Penchants or savours" , "Partakes of" , "Samples the flavour of" , "Tries to determine the flavour of" , "Savours, tests flavour" .)
