Row D is located next to E (7)
I believe the answer is:
dispute
'row' is the definition.
(I've seen this before)
'd is located next to e' is the wordplay.
'located next' becomes 'put' (I can't justify this - if you can you should believe this answer much more).
'd'+'is'+'put'+'e'='DISPUTE'
Can you help me to learn more?
(Other definitions for dispute that I've seen before include "Disagree or challenge" , "Question or deny accuracy or validity" , "conflict" , "Argue about (something)" , "Quarrel over rights" .)
