Quits, still without love (5)
I believe the answer is:
evens
'quits' is the definition.
(as in 'call it quits')
'still without love' is the wordplay.
'still' becomes 'even so' (both can mean nevertheless).
'without' indicates named letters should be taken away.
'love' becomes 'o' (love means zero in tennis).
'evenso' with 'o' taken away is 'EVENS'.
(Other definitions for evens that I've seen before include "Kind of bet where odds are one to one" , "Oddly, these could be odds" , "decreases" , "less likely than 27 [ODDS-ON]" , "Odds on something very likely to win" .)
