Love quest oversight (8)

Ross

I believe the answer is:

omission

'oversight' is the definition.
(omission is a kind of oversight)

'love quest' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'quest' becomes 'mission'.
'o'+'mission'='OMISSION'

(Other definitions for omission that I've seen before include "cut?" , "It may create space" , "Something lacking" , "Something left out or neglected" , "Negligence" .)

I've seen this clue in the Sydney Morning Herald.
