Reject some love tokens (4)
I believe the answer is:
veto
'reject' is the definition.
(thesaurus)
'some love tokens' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'VETO' is hidden within 'love tokens'.
(Other definitions for veto that I've seen before include "Right of rejection" , "Refusal to assent" , "UN rejection" , "bar" , "Right to reject a decision" .)
