Remote school denied sandwiches (5)
I believe the answer is:
olden
'remote' is the definition.
Both the answer and definition are adjectives. Maybe there's an association between them I don't understand?
'school denied sandwiches' is the wordplay.
'sandwiches' indicates a hidden word (the answer is sandwiched in by the clue).
'OLDEN' can be found hidden inside 'school denied'.
Can you help me to learn more?
(Other definitions for olden that I've seen before include "Of past (times)" , "Out of date" , "Of a former age" , "times gone by" , "Bygone" .)
