Do without love and avoid being fool (6)
I believe the answer is:
delude
'being fool' is the definition.
(thesaurus)
'do without love and avoid' is the wordplay.
'without' suggests deleting specific letters.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'and' is a charade indicator (letters next to each other).
'avoid' becomes 'elude' (eluding is a kind of avoiding**).
'do' with 'o' removed is 'd'.
'd'+'elude'='DELUDE'
(Other definitions for delude that I've seen before include "Kid" , "Mislead; deceive" , "Cause to believe a lie" , "Mislead in belief" , "Fool, deceive" .)
