Crossword Genius

Miss ending after missing beginning (4)

Ross

I believe the answer is:

lose

Here is my best explanation:

'miss' is the definition.
(thesaurus)

'ending after missing beginning' is the wordplay.
'ending' becomes 'close' (close is a kind of ending).
'after missing beginning' means to remove the first letter.
'close' with its initial letter removed is 'LOSE'.
