Completes and corrects without yours truly (4)
I believe the answer is:
ends
'completes' is the definition.
(I've seen this in another clue)
'corrects without yours truly' is the wordplay.
'corrects' becomes 'emends ' (I've seen this before).
'without' indicates named letters should be taken away.
'yours truly' becomes 'me' (the person who set this crossword).
'emends' with 'me' taken away is 'ENDS'.
'and' is the link.
(Other definitions for ends that I've seen before include "Odds and --" , "See 8" , "Wanting goals" , "Terminates, concludes" , "Brings to a close" .)
