Difficulty about love (5)
I believe the answer is:
adore
'love' is the definition.
(adoring is a kind of loving)
'difficulty about' is the wordplay.
'difficulty' becomes 'ado' (ado is bother or difficulty).
'about' becomes 're' ('re' means regarding or about).
'ado'+'re'='ADORE'
(Other definitions for adore that I've seen before include "Worship, idolise" , "Worship, venerate" , "Love to distraction" , "Respect deeply" , "Worship and glorify" .)
