'Break the date, anyhow,' one said again (8)
I believe the answer is:
restated
'one said again' is the definition.
(I've seen this before)
'break the date anyhow' is the wordplay.
'break' becomes 'rest' (rest is a kind of break**).
'anyhow' is an anagram indicator.
'date' anagrammed gives 'ated'.
'rest'+'ated'='RESTATED'
(Other definitions for restated that I've seen before include "Said again" , "In other words" , "Iterated" , "Didn't tell us anything new" , "Declared, not for the first time" .)
