Love possibly to read about love! (5)
I believe the answer is:
adore
'love' is the definition.
(adoring is a kind of loving)
'to read about love' is the wordplay.
'about' is an anagram indicator.
'love' becomes 'o' (love means zero in tennis).
'read' anagrammed with 'o' gives 'ADORE'.
'possibly' acts as a link.
(Other definitions for adore that I've seen before include "Cherish" , "Love, worship" , "Worship, venerate" , "Honour" , "Like a lot" .)
