Love to have a party again (5)
I believe the answer is:
adore
'love' is the definition.
(adoring is a kind of loving)
'a party again' is the wordplay.
'party' becomes 'do' (do can informally mean a party).
'again' becomes 're' (prefix meaning 'again').
'a'+'do'+'re'='ADORE'
'to have' is the link.
(Other definitions for adore that I've seen before include "Worship and glorify" , "Cherish" , "Love greatly" , "Respect deeply" , "Love (someone) deeply" .)
