Before noon in a Mediterranean island, go for a speciality repast (5,3)
I believe the answer is:
cream tea
'a speciality repast' is the definition.
The definition suggests a singular noun which matches the answer.
'before noon in a mediterranean island go' is the wordplay.
'before noon' becomes 'am'.
'in' indicates putting letters inside.
'a mediterranean island' becomes 'crete' (I've seen this in another clue).
'go' becomes 'a' (I am not sure about this - if you are sure you should believe this answer much more).
'am' put inside 'crete' is 'creamte'.
'creamte'+'a'='CREAM TEA'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for cream tea that I've seen before include "Afternoon meal - macerate (anag)" , "snack" , "calorie-packed meal" , "afternoon treat" , "Light afternoon meal" .)
