Refuse to accommodate husband's party (6)
I believe the answer is:
thrash
'party' is the definition.
(thrash can informally mean a party)
'refuse to accommodate husband's' is the wordplay.
'refuse' becomes 'trash' (I've seen this in other clues).
'to accommodate' indicates putting letters inside.
'husband' becomes 'h'.
'trash' placed around 'h' is 'THRASH'.
(Other definitions for thrash that I've seen before include "Flog; party" , "Trounce, beat soundly" , "Whip repeatedly" , "Administer severe beating to" , "Noisy, lavish party" .)
