Repaired a large number and finished (6)

Ross

I believe the answer is:

mended

'repaired' is the definition.
('mend' can be a synonym of 'repair')

'a large number and finished' is the wordplay.
'a large number' becomes 'm' ().
'and' says to put letters next to each other.
'finished' becomes 'ended' ('end' can be a synonym of 'finish').
'm'+'ended'='MENDED'

(Another definition for mended that I've seen is " Repaired, fixed".)

I've seen this clue in The Globe and Mail.
