Spades placed in long row (7)
I believe the answer is:
dispute
'row' is the definition.
(I've seen this before)
'spades placed in long' is the wordplay.
'spades' becomes 's' (abbreviation in card games).
'placed' becomes 'put' (I've seen this before).
'in' means one lot of letters goes inside another.
'long' becomes 'die' (to long for or to die for something is to crave it).
's'+'put'='sput'
'sput' put into 'die' is 'DISPUTE'.
(Other definitions for dispute that I've seen before include "conflict" , "Question or deny accuracy or validity" , "Argue about (something)" , "Row" , "Quarrel over rights" .)
