Contention for every one receiving right puzzle (10)

I believe the answer is:

wordsearch

'puzzle' is the definition.
(I know that wordsearch is a type of puzzle)

'contention for every one receiving right' is the wordplay.
'contention' becomes 'words' (both can mean an argument).
'for every' becomes 'each' (I've seen this in another clue).
'one receiving' means one lot of letters goes inside another.
'right' becomes 'r' (common abbreviation).
'each' enclosing 'r' is 'earch'.
'words'+'earch'='WORDSEARCH'

I've seen this clue in The Independent.
