Loves a party, with others finishing early (6)
I believe the answer is:
adores
'loves' is the definition.
(adoring is a kind of loving)
'a party with others finishing early' is the wordplay.
'party' becomes 'do' (do is a kind of party).
'with' means one lot of letters go next to another.
'others' becomes 'rest' (I've seen this before).
'finishing early' means to remove the last letter.
'rest' with its final letter taken away is 'res'.
'a'+'do'+'res'='ADORES'
(Other definitions for adores that I've seen before include "Worships as divine" , "holds dear" , "Idolises" , "Loves; reveres" , "Soared (anag.)" .)
