Date on end of contract roughly marked (7)
I believe the answer is:
notated
'marked' is the definition.
(I've seen this before)
'date on end of contract roughly' is the wordplay.
'end of' indicates one should take the final letters.
'roughly' indicates anagramming the letters.
The final letter of 'contract' is 't'.
'date'+'on'+'t'='dateont'
'dateont' with letters rearranged gives 'NOTATED'.
(Other definitions for notated that I've seen before include "wrote music?" , "commented on" , "Set down in symbols" , "Marked" , "Written like a music score" .)
