Part of supermarket beer is stocked (5)
I believe the answer is:
aisle
'part of supermarket' is the definition.
(I've seen this before)
'beer is stocked' is the wordplay.
I cannot really see how this works, but
'is' is present in the answer.
'beer' could be 'ale' (type of beer) and 'ale' is located in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for aisle that I've seen before include "Passages between seating areas" , "part of theatre?" , "Passage between blocks of chairs" , "way to the altar?" , "Way between seat blocks" .)
