Make even (3)
I believe the answer is:
tie
'make even' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tie that I've seen before include "Finish level" , "'Fasten, with string say (3)'" , "Attach, fasten" , "Fasten a parcel" , "Restrict; fasten" .)
