Love calling for exclusion (8)
I believe the answer is:
omission
'exclusion' is the definition.
(thesaurus)
'love calling' is the wordplay.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'calling' becomes 'mission' (I've seen this before).
'o'+'mission'='OMISSION'
'for' acts as a link.
(Other definitions for omission that I've seen before include "Failure to include" , "A thing left out" , "lapse" , "cut?" , "Oversight, piece of work neglected" .)
