Are out to cheat of love (5)
I believe the answer is:
adore
'love' is the definition.
(adoring is a kind of loving)
'are out to cheat' is the wordplay.
'out' means one lot of letters goes inside another.
'to cheat' becomes 'do'.
'are' placed around 'do' is 'ADORE'.
'of' is the link.
(Other definitions for adore that I've seen before include "Respect deeply" , "Love (someone) deeply" , "Worship, idolise" , "Honour" , "Very much like" .)
