Read "Running from one side to the other is a pantry" (6)
I believe the answer is:
larder
'a pantry' is the definition.
(synonyms)
'read running from one side to the other' is the wordplay.
I cannot really see how this works, but
an anagram of 'read' is 'arde' which is present in the answer.
'side' could be 'r' (abbreviation for right) and 'r' is found in the answer.
A single letter 'l' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'is' is the link.
Can you help me to learn more?
(Other definitions for larder that I've seen before include "Place where food is kept" , "Food storeroom" , "Food store" , "Room or cupboard for storing food" , "Person applying grease" .)
