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.
'running' indicates an anagram.
'from' means one lot of letters go next to another.
'one side' becomes 'r' (abbreviation for right).
'to' says to put letters next to each other (I've seen this in other clues).
'the other' becomes 'l' (I can't justify this - if you can you should give a lot more credence to this answer).
'read' is an anagram of 'arde'.
'arde' put next to 'r' is 'arder'.
'arder' after 'l' is 'LARDER'.
'is' acts as a 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" .)
